I'm Super Yoshi Bro's friend from school, and i have seen everyone of his comics so far.
they are:
A) NOT a copy off of Billy & Mandy (although the themes are a bit the same)
B) REDICULOUSLY FUNNY (i bet half of you people will say that they suck just so you can be mean)
WE'LL SEE WHO'S MOCKING WHO WHEN HE IS MAKING MILLIONS OFF OF THIS IDEA!
PS: Don't worry SYB, i got your back. All these people are noobs!
