In Viper's Lair

The "sequel," of sorts to Trek Through the Swamp. Having made their way through the deepest recesses of the swamp, Dr. Viper and his "guests" arrive at his tree lair. Once inside the main chamber (the hollow of the gigantic tree), Viper lays down the law to a very distraught-looking Dr. Zyme. Namely, that he's going to be his unwitting assistant in his evil schemes to take over Megakat City.

This took quite a lot of work to draw, although not quite as much work as the previous picture of them walking through the swamp. I based the design of the lair - the stairs coming up from the floor, the bottles and stuff crammed into knotholes, etc. - off of how it appeared in the only episode we saw it in, The Giant Bacteria.
