what if Garth and Lilly did have pups?

I think that would've been really cool

that would be interesting and to see them have first cousins

I really did wish Garth and Lilly did had pups in the sequels because it would've been nice to see Claudette, Stinky and Runt have cousins who can go on adventures with them. Plus, not only would it make Tony a grandfather, but Lilly and Garth would've gotten lebih involved appearing lebih often in the sequels too just like Kate and Humphrey did.
