While getting some Sponge Fog to counter act the Ultrasolvin acid, which was threatening Cats Lair. The ThunderCats found themselves under attack by the Rockmen up on the Pass of the Rockmen, a mountain ridge north of them. The Rockmen threw boulders on them below, but managed to get out of there and protecting the ThunderTank with the Sponge Fog they had gotten. They ended up leaving the area of the Rockmen and crossed into the Forest of Giant Insects.
