Tails was flying the Tornado, his yellow plane, you're in the backseat and Sonic is standing on the nose as usual until he started potty dancing and blushed a bit

Sonic: Tails, can we land for a pit stop?

Tails: Alright. How bad is it?

Sonic held his 'little buddy' and potty danced harder Tails eyes widened, understanding the urgency of how badly Sonic had to go.

Tails: OK! OK! I'll get us a potty break ASAP!

Tails looked for a safe landing spot. Now the question is....do you need a pit stop too?
