Character Designs

When Dib's plans of spending Summer break spying on Zim is crushed by his dad sending him away to a small town called Gravity Falls he soon discovers his dad unknowingly sent him to a place Dib could only dream of. Dib meet's Mabel and Dipper during his stay and immediately becomes fast friends with the Mystery Twins. But it dosen't take long for a certain Irken to get bored without Dib back home that the Irken soon decides to take his own trip to Gravity Falls.

I'm going through a huge Invader Zim and Gravity Falls phase rn so I thought why not make a crossover of the two shows.
(DISCLAIMER) I don't own either of these amazing shows
