Word is, they're looking for the other 25 monkeys and their typewriters

So it seems these fifteen monkeys escaped from a wildlife conservation facility in Lakeland, Florida. How they got the ski masks and commandeered a trolley car is anyone's guess.

Seriously, they got off their island by swimming across a pond. We can imagine how the conversation went at the orientation session:

"All right, you monkeys. You live on this here island. Right?"

"Ooh. Ooh!"

"Right. Now listen. The only thing keeping you here is this small stream that separtates you and the mainland. You're not going to swim across it, are you?"

"Aah. Ah!" (A few moments of bug picking).

"Good. Nighty-night." (Zookeeper exits)

Monkey 1: What a schmuck.

Monkey 2: We grew up in the jungle with trees and rocks and predators. He grew up in the 'burbs where the most dangerous thing was really hot latte.

Monkey: We break out tonight.

And you know the rest.
