the bait

Now that Trouble is back, the limiting factor on bear and elephant acquisition is just the availability of those of the Animorphs who experience nonzero parental supervision. There is a coincidence of Renée being out well past zoo closing time and Robin's mother being occupied the day after Trouble's return.

Everybody morphs pigeons and they fly to the zoo. The three of them that are going to get bears head for the bear enclosure, and Trouble, of course, is the bait.

the airplane

Bella, Andi, and Robin all get on the plane. Bella and Robin have toothbrush caps in their pockets containing flies. Nothing in particular happens when they go through security. They fly for an hour, and then Bella, rather than risk crunch time due to turbulence or a line for the bathroom a little later on, gets up to take Trouble into privacy for demorphing and remorphing.

She takes the toothbrush cap out of her pocket and sets it on the tiny little counter, and then flattens herself against a wall to give him room.
