Mosh was a circus animal before the Zillas ended up with him.
We see in "Meet The Zillas" and "Big Willy On Campus" that he does tricks with a ball, which are typically tricks done by animals at the circus. Also he's pretty smart for a lizard and knows all kinds of tricks that a dog would. It's possible he was part of a travelling circus before the family found/adopted him (it's never mentioned where exactly they got him from) Episode plots they could have done if the show was renewed for more seasons:
- A Loony Fan obsessed with Rock stalks the Zilla family.
- A Behind the Music style episode about Rock Zilla's music career.
- Origin story of how the family got Mosh.
- An episode where Willy tries drugs or alcohol (Braceface did it and that aired on the same channel) In that episode Rock would get mad at Willy for the first time in the entire series for doing something so reckless and stupid (similar to Sharon's father in said Braceface episode)
