Welcome to my studio You can use crossovers characters in 2d just by pressing the crossover buttons if you want.
Sorry for the panel 2 and 6's peppino's pants and shoes have not yet colored. (Count as the errors.) It seems that peppino and bubbles aka Barry have been meet professor candy again. And this time professor candy has been created robo Barry/bubbles (is basically based on regular Barry/bubbles) as a distraction. Can bubbles/Barry able to fight this robo counterpart?
