Front Cover: Cassie morphing into an anteater.
Inside Front Cover: Cassie Anteater with a bunch of Helmacrons stuck to her tongue. She is in the anteater pen with one other anteater (possibly either Visser Three or another animorph). There are 7 people watching the anteater pen.
PP 152-153: Having checkmating both the Helmacrons and Visser Three, the Animorphs go to work. Anteaters Rachel and Jake lap up the Heklmacrons and hold them hostage, while Ax holds Visser Three hostage, and guards the Helmacrom ship and the morphing cube. Marco and Cassie demorph to miniture human form, go into the Helmacron ship, and start unshrinking everyone. They first unshrink Visser Three, Tobias, and the Human-Controllers. Visser Three and the Human-Controllers depart. Then Rachel and Jake scrap off their Helmacrons, demorph, and are unshrunk. Then Marcos and Cassie put the beam on automatic and stand in it.
How in the world do Visser Three, the Human-Controllers, Ax, the Animorphs, and the Helmacron ship leave without the 7 sightseers noticing them? Those 7 visitors on the inside front cover should have seen 2 Andalites, a bunch of humans, and a red-tailed hawk appear out of nowhere!
