Take the Plunge: Part 1 is the first part of the first episode of Battle for Dream Island.
Twenty animated objects are told by a talking speaker, that they can win Dream Island, a 1-square-mile island with luxurious facilities, a casino, robot servants, and a 5-star hotel that includes 6 restaurants. They compete in a challenge, believing that the winners would obtain the island. Two of them win, only to be told that they pick the teams for upcoming challenges, thus beginning the battle for Dream Island.
Before the Intro
The first scene shows Pencil and Match discussing how Flower is afraid of bugs. They are soon interupted by Ice Cube, who wants revenge on Flower for kicking her for commenting that Flower is not beautiful. She then says she's glad that Pencil and Match are her friends, then accidently pops Bubble (who is also her friend) while giving her a hug. Bubble comes out of the Bubble Recovery Center, only to nearly be popped by Pin.
It turns out that Blocky was holding her, and after she breaks free, he throws Needle at Bubble. He says that he only wanted to hurt someone, then he kicks Woody, almost hitting Teardrop. Leafy picks him up, and tells him to enjoy life. He tries to hug Teardrop, but instead gets kicked again. Tennis Ball tells Teardrop to calm down. Woody hits Rocky, chipping himself in the process. Woody screams in pain, while Eraser and Pen comment that Woody is not cool. Eraser said Pen is cool, and Pen says that Eraser is cool too. Snowball's hang glider hit into a mountain, and on his way down, finds Rocky, and he shakes Rocky. After a one-sided greeting, he throws him at Tennis Ball, who frowns at Rocky. Rocky says hi to Tennis Ball, calling him his "good ol' friend".
Meanwhile, Coiny and Firey fight on top of Spongy, who is giving off some water. Golf Ball tells them to stop fighting, and for Spongy to take a bath because he smells stinky. Eraser and Blocky discuss about Golf Ball's bossiness, and Eraser calls her a "bossy-bot", or a robot who is built to be its bossiest. Eraser says that he'd do anything to get away from Golf Ball, Flower, Woody, and Spongy.
Everyone is placed onto a wooden balance beam, and the Speaker informs that who stay the longest on the bridge wins. Leafy and Pin promise to "help each other". Blocky sits still in a pose, which Coiny notices and wonders what he is doing, and tells him to wake up. Spongy falls first after slipping out of place. Woody, Eraser, Tennis Ball, Firey, Golf Ball, Needle, and Leafy are aggressively pushed to their deaths by Flower, saying that she "needs her space". Leafy is saved by Pin right before reaching the water.
Bubble decides to form an alliance along with Pencil and Match that will last throughout the entire series. Ice Cube, eager to secure her friendship with them, asks if she could join, but slips at extreme speed towards them, making Pen fall, and she hits Snowball. SB and the rest of Pencil's alliance fall. Before sinking into the water, Pencil rejected Ice Cube's request.
Coiny, having noticed that Blocky is still not moving, and tells him to wake up again. He shakes Blocky, accidentally causing Blocky to fall off of the bridge, but Blocky comes back backwards, and makes Coiny fall. Blocky tells him to not mess with him, but he is too late.
With six of them left, Leafy and Pin try to push off Flower, while Blocky watches them fearfully. However, Flower notices them on time and kicks them easily to the air. Although they were now amazed by their "flying" (Eraser can be seen on the background at this point), unfortunately they end up crashing into the bridge and knock themselves and Teardrop. Leafy saves everyone by holding on to the bridge and one another. Leafy calls Blocky or Rocky for help. Leafy almost loses a grip of the bridge, but luckily, Blocky comes, only to step on her feet. He realizes his mistake and pulls Leafy's arm, but he ends up by all of them hanging on the bridge. Leafy tells Teardrop to reach on her other arm to conserve their weight so Blocky can pull them up easier. Flower comes and shows off her Non-Slip Shoes So Ha, but Blocky uses one of his feet and kicks her off the bridge. Flower holds on to Pin in time, so Pin uses her tongue to lick Flower. Flower has disgusted by Pin's tongue gradually loses grip of Pin and finally falls into the water. Leafy said to Pin that dropping Flower was a job well done. Pin and Teardrop swing back to the bridge. Leafy reminds Pin that they have an alliance, so she helped Leafy swing back to the bridge. Blocky says that Leafy is stepping on him but just like his attempt to help Coiny up, Leafy realizes it at the last minute and Blocky falls off the bridge. Later, Teardrop tries to push off Rocky, but she slips and falls, along with Rocky.
Leafy and Pin are deemed winners, so they made a rock-paper-scissors tie-breaker, and Pin was the winner since scissors cuts paper. They argue about the bias, but the Speaker turns up to them and says that they both win. Pin is confused and asks that they both get the island, but it turns out that they are going to be team leaders of the future teams for a longer competition to win the island. Pin seems to be bored.
- While Pin and Leafy were flying in the air, Eraser is seen flying in a distance for a very very very brief moment even when he was pushed by Flower.
- This is one of the three BFDI episodes with no voting, the other two being Puzzling Mysteries and Return of the Hang Glider.
- Apparently there was an alternate ending to the contest Teardrop was still in and Leafy was out then Pin knocked off Teardrop and won. Apparently the voices were done but it was deleted probably due to timing.
- Spongy was so big, he had to be pressed very tightly so he can out of the tube to get on the balance beam.
- There were 2 words that said "HELP" between Pin and Leafy. One of them was red, and the other was green. Both word colors represent Pin and Leafy respectively.
- This episode has the most views (more than 45 million views), and has the highest dislike/like ratio (with 29,000+ likes and 9,000+ dislikes).
- During the beginning, Pencil was originally supposed to say "Really, Match?"
- The claws resemble the claws from The Demented Cartoon Movie.
- Before Ice Cube pops Bubble, if you play it backward, you will hear Ice Cube said "Over here".
- This is the first ever episode to have subtitles, the second being Lofty, the third being The Long-lost Yoyle City, and the fourth being Welcome Back.
- Eraser's voice becomes Blocky's voice in future episodes. Probably due to the fact the voice actors were closely into hitting puberty.
- The same thing happens to Blocky where his voice becomes Pen's voice.
- Needle, Pen, Snowball, and Tennis Ball appear a few times on-screen, but each only has a single line.
- This is the first official appearance of the Non-Slip Shoes So Ha shoes (worn by Flower). It makes its second appearance in Insectophobe's Nightmare 2.
- This is the only episode to use the "snatch" sound effect.
- When Pin says "only one of us can win", it is implied that she accidentally flips Leafy the middle finger, as Leafy responds she flipped the "wrong finger".
- When Ice Cube gets kicked by Flower, her legs disappear.
- There was a shadow under Blocky, then it's mysteriously disappeared when he turned around.
- When Pin was getting up, her arm wasn't attached to her body.
- When Flower held on to Pin, her arm wasn't attached to her body.
- At 3:07, when there was sunshine, Blocky, Snowball, Pen and Eraser were armless.
- When the scene changed to Spongy, Firey and Coiny were armless and faceless. However, when it moved up to them, their arms (except Spongy's) and face have just appeared from nowhere.
- After Eraser explains to Blocky about Golf Ball is a "bossy-bot", Pen and Snowball appeared out of nowhere. It is possible that they joined Blocky immediately.
- At 3:45, Eraser is armless.
- At 4:28, the characters' sizes were incorrect.
- Leafy's voice changed throughout the episode.
- Bubble should've popped when Ice Cube bumped Pencil's Alliance because her bump was too strong.
- Bubble popped when Ice Cube squeezes her to hard.
- Firey most likely died in the water when he is pushed off the balance beam by Flower.
- The 18 contestants that fell in the water most likely drowned. (Debatable except Firey.)
