REINCARNATED BY ANUBI
Two words: Delicious candy.
Shak refers to his dorsal fin as his “comb over” because it usually flops on one side. Whenever Shak gets angry with other cast members he “chomps” down on them - usually also yelling out “CHOMP!” while doing so. If the cast member is too far away to be chomped, we can typically witness a flying shak immediately before that.
Shak is voiced by Terry.
Terry created the character with the idea in mind that he would be the dumbest cast member around - his fellow cast members often prove that this is quite impossible.
