Nessa recently brought you to a secluded spot in her gym to spend some time with you. While there, she wanted to show you a cool trick.

Wanna see how much water I can drink?

She takes a five-gallon jug and drinks almost all of it in one sitting. When she finishes, her belly is bigger and rounder than a beach ball, and her belly chain has snapped off.

Hehe... A pro Pokémon trainer should never underestimate the importance of water.
