You received a letter from Muscle Planet asking for your aid. After boarding a space craft to the planet, various embassadors take you to a wrestling gym. Once inside, they leave you with a short man in a mask, cape, and diaper.

“Sorry to ruin your quiet time, but we’re in a bad place right now. The dMp is planning to destroy this planet as we speak, and we needed some help. I can teach ya a few moves to defend yourself.” He then gets into a wrestling ring and signals for you to get in.
