Bella pats the bear she is sitting on. "This one morphs you. That one," she points at Ethan, "assuming I haven't mixed them up, mauls him and drags him off to the nearest water source, then this one demorphs, all better, he doesn't mind getting mauled. We find park rangers and tell them a bear attacked you and we barely got away. The tracks are right, the blood is right, etcetera. Meanwhile, we make you morphable, you turn into some kind of bug or something else we can catch here, we take you someplace you can hide out - probably back to Phoenix, ultimately."
"Trouble's been being a pigeon a lot," adds Andi. "You can... be pigeons... together?"
Bella checks her watch. "Bears may as well demorph now," she remarks, "even Ethan, low on morph time - who wants to check again for park rangers?" She slides awkwardly down Trouble's side.
Trouble rubs the side of his big furry head against her shoulder in a gentle friendly sort of way and then starts to demorph.
"Thanks," says Bella to Robin. "Okay. Dad, do you have a better idea than ours?"
He shakes his head slowly. "I didn't - think I was ever going to get rid of him, I don't have a plan. And we should hurry in case anyone at the Seattle pool notices I'm not showing up."
"Okay. Back to the picnic stuff for the box, then you let Trouble acquire you, they try for their Oscars, we leave some of your stuff around - Andi has your bullets, you can reload the gun, maybe fire at a tree to make it plausible that you tried to hit the bear and missed, leave it on the ground. Then you turn into whatever's handy and little and me and Andi go act hysterical."
Bella takes the box out of its layers of obfuscation and takes Charlie's hand and puts it on a side.
He twitches a little when it zaps him. "That's it? That's the big Andalite morphing tech?"
"Yeah. User-friendly, huh?" She wraps it up again. "Shake hands with Trouble, you'll go kind of sedated - and then you're going to have to give him most of your clothes. If you were wondering why me and Andi are dressing like shrinkwrap is the new fashion it's because it's easier to incorporate snug outfits into a morph."
Charlie's eyelids droop and his posture slumps when he's acquired, and then he comes around. He sighs and starts handing over clothes. "You go behind a tree or something when you morph," he tells Trouble, "all right? And - I did that 'cause Bella has a plan, not necessarily okay with being turned into for... plan-unrelated things."
"Bug-hunting time," Bella announces, and she starts looking for bugs.
Trouble snorts. "I'll be just as happy to never turn into you again," he says, accepting the clothes.
Eventually Charlie is standing in his underwear, looking for bugs with his daughters, muttering under his breath. "What's the plan for dealing with Esclan?" he asks.
"Is that your Yeerk? We can bury it. You might want to acquire it first - the rest of us have a different one, we don't know when it'll come in handy but it's the sort of thing with better odds of doing so than, like, earthworms."
Charlie hikes back to where his Yeerk slipped out, manages to acquire it, and then gets a stick and digs a hole to dump it in and cover with leaves. Then it's back to bug-hunting.
Andi finds a tiny, unremarkable black beetle, which she presents to Charlie.
He acquires that too. "How many of these can I do?" he asks as he loads his gun up again.
