yep, but ur a yohhi fox, and he's a yoshi. so he's the biggest yoshi around (unless there's a bigger one somewhere) and ur the biggest yoshi-fox around.
there is a difference between a yoshi and yoshi-fox. one is a normal yoshi and the yoshi fox has ears and in ur case 2 tails that look like there from tails from sonic.
ur right about being the biggest yoshi fox though.
