Nukus releases Les Fortunes' latest creation, Hagfish of Gar, a fish-like creature. Forewarned by Wolfie's keen hearing and Fangula's knowledge of the ancient myth, the kids have Art create Sector Cycles. The cycles provide the kids with the advantage they need to save themselves and all the children of Charterville from the evil clutches of the Crustaceans.—Anonymous
The Crustaceans summon the Hagfish of Gar, a monster who can put children under its control with its song as well as spew slime, and Nukus attempts to use it to brainwash all the children of Charterville (including Drew, Jo, and Roland) by sending them through an "Evil Archway".
