Adding the Chain Chomp for Baby Mario Bros.

[Illimvra]

I am making a Baby Mario Bros PSA, and I wanted to replace something with a Chain Chomp so I could use it in their entrance, and some of their attacks.

Could I replace their rubber string article (if so, how)?

Could I replace the Condor that drops them off in their Entry (and would I be able to make the Condor/Chain Chomp reappear after entry?)?

Would it be possible at all?

Thanks for reading!
