Leo: Well, how about as a birthday gift you give me a bionic ability?

Donald: Or I could gift-wrap reality and you could play with that for a while.

Chase: Eddy, we're moving the party prep upstairs. Keep Leo in the lab until I give you the signal.

Eddy: Wait. So you want me to hold the poor kid against his will? I'm in!

— Chase and Eddy
