ThunderCats Roar - Season 1 - Eps 21: Summer Fun Day
The Thundercats are exhausted from fighting bad guys all the time so Lion-O suggests they spend a relaxing summer fun day at the beach, with no fighting. Unfortunately the beach is home to the Crabmen, giant, clawed humanoids that fight anyone who steps on their sand. Looks like summer fun day might involve some fighting.
