The package part 2

"Fine, unless it's brains then I don't want any!"

"Why would he write "Huh" on a paper? I don't know Marble, but this uncle of ours isn't really smart. Maybe his brain is in the box!"

Do you see anything Phillip?

"Nope."

"Maybe it is at the bottom. Go in and check."

"I am not going in there to be eaten by invisible brains."

"Come on Phillip, you are just the right size! I promise to pull you out as soon as you say our code phrase."

"What's the code phrase?"

"Uncle Bert needs a new brain."

"Fine!"
