When Plankton scraps the Chum Bucket and builds the Imperial Chum Coliseum in its place, it isn't long before SpongeBob and Patrick become gladiators for the Coliseum's big show in this goofy spoof of Spartacus from the hit animated series. Also in this collection, Squidward tries his hand at composing music; Plankton, Squidward, Patrick and SpongeBob start a rock band; and Mr. Krabs finds a deeper relationship -- with his money!
