In this episode, the characters all wish for various things. Here's a list of what each dinosaur wished for:
Steggy: A pair of earmuffs
Pterence: To be the boss of everyone
Taury: To be huge
Sid: To be fun
Patsy: To be not so sensible
Trike: To be super smart
Normally the first sentence Harry says is the title. Because the first thing Harry said in this episode was "I wish it wasn't raining," the title was only "I Wish!" which is more reflective of what the epsiode's about. That title also would have been too similar to the title of " I Wish It Would Stop Raining!"
Wishing Well: It's always the same old story. No one bothers to read the fine print. One wish will be held back in case of emergencies. Remember, Harry, that's your last wish!
Pterence: I want to wish.
Harry: I wish you'd just go away. (Pterence disappears.)
Harry: This wishing business isn't working out the way I hoped.
Taury: (loudly) Trike shouldn't get a wish if he's going to waste it on something stupid.
Trike: Stupid? You're calling me stupid? I'll show you. I wish I was super-smart.
Taury: I wish I was humongous. (very loudly) Now that's a wish!
Harry: I think I've gone deaf!
Sid: Yeah, I wish I had some earphones.
Sid: Wishing stones. Each stone is worth a wish.
Harry: Holy moly. Get ready to start wishing, guys.
Wishing Well: (speaking like a game-show host) Well, hello there, harry. So you'd like some wishes. No problem. Lower the bucket and pull some up.
Harry: It's not fair. My wishes never come true. I need to find a place where wishes work.
Sam: I wish you could play guitar.
Harry: I wish Sam wasn't such a know-it-all.
The events of "I Wish!" resemble the Dragon Tales story "One Big Wish" in that in that story, the character Max made a wish on a well named Willie. However, he didn't realize he had made a wish. They also somewhat mirror the recent Care Bears CGI feature Big Wish Movie, in which the character Wish Bear misuses the power of her wishing star Twinkers.
Taury and Trikes' argument over whether the Dino World sun should be red or duck-egg blue (as well their subsequent wishing over and over for each color) is simliar to the behavior of the fairies Flora and Merryweather in the Disney classic Sleeping Beauty. They couldn't agree on the color that Princess Aurora's dress should be and so Merryweather kept using her wand to make it blue, while the Flora kept using hers to make it pink.
