Names of *the frog* (OTGW)

In Over The Garden Wall (which you should see, probably), the first episode starts with Greg enumerating rejected names for the frog:

“Wait, wait a second […]”

At the end of the first episode, the frogs name is “Wirt”, which is also the name of Greg’s brother, who will henceforth be called “Kitty”. (Which is also my name, by the way.)

“What, maybe I’ll start calling you ‘Candypants’.” - “Woah, yeah!”
