I dub this episode The Ooo Before Time.

Jake: They devolved into beasts! It was hilarious!

That ending scene with PB and the monitors reminded me of The Dark Knight movie where Lucius Fox shut down the surveillance system.

About the Finn in the Finn sword, he mentions the last name Mertens which I wonder where he had gotten that and is it now officially his last name (presumably given by Jake's parents)? I mean I know about the connection with Farmworld Finn from the season 5 premiere but still.

I want a 'I <3 bunny' shirt. Team Bunny > Team Edward and Jacob.

Just like to point out that Finn's stem palm after the events of Breezy has been shown, which could foreshadow and lead to something down the line involving Finn's new sword and the Grass Blade curse. Maybe that leads to robotic arm in the near future or some cool fusion of Finn sword and Blade of Grass/grass magic…

Hmm…how the monster bit Joshua to get him impregnated could explain how Lady Rainicorn had gotten pregnant. When?

I think Jake's true birth was possibly hinted/clued before…When was it?
