"An amphibian capable of calling up a massive tidal wave from the dark seas to wipe out enemy monsters."

In Capsule Monsters Tristan has pretty good observational skills--hearing the Gokibore from the vibrations on the ground when they bounced,  figuring out how the Capsule Rocks work, realizing the bugs didn’t follow them to the beach cause Root Water was there, noticing Yami Yugi’s exhaustion, and drawing his face on the maze wall to mark his progress.

From Capsule Monsters, Tea dodges one of Root Water’s blasts :D

i love how Tristan thought Root Water appeared because Tea touched a capsule rock XD It’d be hard for it to get around without any water!
