The Cosmic Frog: Find Muck expansion adds mental powers to the game so that your frog is no longer merely immortal and invulnerable, but psionic as well! Mental powers open the way for mental combat and gullet purging.

This expansion also introduces muck lands, special terrain tiles that offer interesting choices for you in the Outer Dimensions and that function as wildcards for vault scoring.

Finally, this expansion introduces a new chip system for combat, raiding, and returning from the Outer Dimensions that allows for some serious metagaming.
