In her appearances, Dora usually speaks a weird, squeaky sped up Spanish. This article list these quotes and what it is.
Dora's voice is a female Spanish voice provided in Google Translate for aloud speech. It is sped up 10x, the only exception is in The Reveal, which she instead blurts out generic cartoon blabbering sped up 20x. The caption "PERFECT SPANISH!!!!!!!!" in yellow stars to her left and right when she speaks. This didn't happen in Get Digging, which subtitles scroll from the bottom.
"My name is Dora and I need the Island very badly because I feed on islands. Islands are my only food, and, as such, I need as many islands as I can get! Many people refuse to sell me islands because they know that I will just gobble them up, and that is true, but what harm would that do to them? We island-eaters are tired of the discrimination we receive from society in general, and would greatly appreciate if just one ray of light was shone on our people in the form of Dream Island!"
"That was a very bad decision you voters made! You'll regret it when i'll starve to death! I'll haunt you in your sleep!"
"I am very glad Fries gave me the shovel, and, with it, the ability to dig. I know that if I can dig, I can create islands! And since islands are my only food, creating islands is very important to me. I love islands so much that I have written my very own island song. Would you like to hear it? Never mind - I don't care about your opinion. I'm going to sing it anyway. It goes - 'Islands, islands! Yum, yum yum! Islands, islands! Chomp. Islands! They are so delish! Gimme islands now! Gimme! Gimme gimme, gimme! Gimme. Islands! Yum! Islands. Glorp. Shlorp! Gobble! Gloop! Gulp! Lala! Islands.' So, what did you think? Never mind - I don't care about your opinion. I know that you, being biased against us island-eaters, will say you hate it. But we island-eaters know that all the songs we write are wonderful. My two favorite things in the world are islands and songs. My two least favorite things are you and David. David is not my brother. He is not even related to me. I have tried to kill him plenty of times, but all my attempts have failed miserably. Most of my failures are the result of the horrendous "David Cloner." I forgot to tell you that the David Cloner ranks third on my least favorite list. Anyway, back to islands. I like islands. They are good. So good, I want to sing my song again! 'Islands, islands! Yum, yum yum! Islands, islands! Chomp. Islands! They are so delish! Gimme islands now! Gimme! Gimme gimme, gimme! Gimme. Islands! Yum! Islands. Glorp. Shlorp! Gobble! Gloop! Gulp! Lala! Islands.'"
