This is a comic strip I came up with years ago and sort of abandoned halfway through (You'll notice that's a really bad habit of mine) The idea behind it was that the Robotnik family were going to the mall for Mother's day to pamper Momma Robotnik. Robotnik gives Scratch and Grounder money to buy his mother gifts and Sonic & Tails (who just so happen to be passing by and overhear the conversation) decide to pull constant pranks on Scratch and Grounder throughout the mall to try and steal the money away from them.
It's just a fun one-off twist where I throw out the idea of who's the hero and who's the villain and just have fun with the characters y'know?
