Yoyleland is a fictional place where yoyleberries are found. Yoyleberries are fictional berries which are used to make yoylecake and yoylestew. It is known to make a jingling sound when eaten.
Yoyleberry and cake eaters are known to turn into Yoyle Metal, an element which is unfreezable.
In Rescission, Bubble, for the first time ever, utters, "Yoylecake!"
Yoyleland and yoyleberries only make an appearance (on the first season) in The Glistening, where Bubble says "yoylecake" when Speaker says that she and Leafy have immunity. Then Leafy says that she has an actual yoylecake made from yoyleberries from Yoyleland. Bubble then ate a slice, which she thought was delicious. During the long jump challenge, Bubble turns into Metal Ball, falling straight onto the sand.
In Don't Pierce My Flesh, yoylecake was used for Cake at Stake. When Bubble fell in the magma during the volcano escape challenge, the metal effect wore of when she came out of the Master Recovery Center. At the end of the episode, all of the remaining players turned into metal. The side effects were so extreme that the remaining contestants had to go to an incinerator to become normal again.
In Get in the Van, the challenge was to reach the summit of Yoyle Mountain on Yoyleland. In The Long-lost Yoyle City where the contestants finally reach Yoyleland, Yoyle City is seen. It's an abandoned city near Yoyle Mountain, and it has a variety of stores and tower that looks like the CN Tower.
- Yoylecake may be a long form of Bubble's other catchphrase Yoy.
- Boombox apparently lives in Yoyleland, as seen in Yeah, Who? I Wanna Know.
- Yoyleland is 2,763 miles from where the 21st challenge was, confirmed in BFDI 21.
- In fact, it appears to be 2,763 miles away from the BFDI contest area in general.
- About 80 feet from the canyon in the Evil Forest, Yoyleland is 2,761 miles away.
- A desert appears to be about a mile away from Evil Canyon. And a decent way into the desert, it seems that Yoyleland is still 2,760 miles away.
- Yoyleland is at a beach on the island over the Goiky Canal.
- When Leafy jumps inside the map she says "Blue's skadoo, you can too!" which is a reference to Blue's Clues.
- In BFDIA 1: Yeah, Who? I Wanna Know, the Yoylemap is seen to have four textings, instead of the regular "You are here", "Yoyleland" and "Goiky Canal" it also said "Dream Island" which shows Pin's stupidness by ripping it in pieces, because in BFDIA 4: Zeeky Boogy Doog the contestans were unhappy about that Dream Island disappeared. Puffball even threw up.
- Yoyle Land has more wild trees than the "city" trees with a total of 179,034,521 wild trees, that really dwarfs the total city trees, 281,164. In that, 27% are Spiky trees, 13% are Green ball trees, 28% are Yoyle bushes and 32% are Pink ball trees.
- Yoyle Mountain has a height of 5,580 meters (18,307 ft.). if it is a real mountain, it would be the 206th highest mountain in the world.

- The total area for the field of Yoyle Stadium is 100x50 meters, the whole stadium is 200x150 meters, but one problem is that each row of seats is 5 meters wide and high, which is unrealistically big.
