Snarf Takes Up the Challenge

Snarf returns to Cats Lair only to find it deserted. He searches but cannot locate any of the ThunderCats. The only one left in the lair isRo-Bear-Bill who himself does not know what happened to the ThunderCats. Suddenly the Female Unicorn Keeper appears and informs Snarf that the ThunderCats have all been captured, which Snarf finds hard to believe.

She continues to narrate that it all started when the Mutants first started herding her Unicorns, causing them to flee into the Forest of Silence. Her husband came to the ThunderCats for help and they split up and went into the forest to find the unicorns. Lion-O was the first one to be captured. He was shackled by the NoseDiver that the Mutants had purposely left unguarded. Tygra was next to fall victim when he entered and was trapped in a Maze of Light. Next in Line was Panthrowho, similarly to Tygra, was imprisoned inside a giant crystal chamber. The ThunderKittens followed suit whenVultureman used a strong tractor beam from Castle Plun-Darr to catch them. Cheetara was the last one to be caught by the Mutants who used a fake ThunderCats signal to lure her into their trap.

Realizing that he is the only ThunderCat left, Snarf embarks on a mission to rescue his friends. Using his ability to communicate with animals, Snarf calls a giant bat who first flies him to Castle Plun-Darr so that he can find out where the ThunderCats are being held captive. There he overhears the Mutants gloating over their success and learns that his friends are all incarcerated inside Mumm-Ra's Black Pyramid so he rides the bat to that location.

Once he reaches the Black Pyramid, Snarf talks to a spider who enters the pyramid through a crevice and proceeds to tie up Mumm-Ra's sarcophagus using its web with the mummy still inside. Snarf then instructs a woodpecker with a diamond tipped beak to bore a hole in the wall of the pyramid and reaches inside the hole to pull the lever which controls the main doorway.

With the door open, Snarf rushes into the pyramid where he finds all the ThunderCats mummified. He quickly tears the bandages covering Lion-O and hands him the Sword of Omens who uses it to free the other ThunderCats and they all leap into action. By this point, Mumm-Ra who had been struggling to emerge from his web bound sarcophagus, finally manages to open it and transforms into this ever-living form. He then fires energy bolts from his hands at Lion-O who avoids some of them and uses the sword to deflect the others. Mumm-Ra then charges at Lion-O but the young lord uses the sword's blade to show Mumm-Ra his own reflection which causes him to recoil in fear back into his tomb.
