Day of the Toads

The next volume in this branch of humorous stories happening between the first and second volumes of Zenith presents two stories. In the first, the Dungeon is attacked by a swarm of enormous flying venomous toads. The Dungeon almost succumbs as the toads seek to get free rein inside! In the second, herbert is sent on a mission to clear out the septic tank, which hasn't been done for 40 years. Turns out the crap has accumulated so massively a whole beautiful ecology has formed in the basement. Should this flowery dung heap be destroyed?
