Finn and Jake battle Spongebob and Patrick in 3 spots:
- Sandy's treedome.
- On the beach.
- In Khazan.
Which side will win a prolonged battle?
Assuming size equalization and water domes for Spongebob and Patrick, I still go Finn and Jake... Patrick's intense stupidity *could* be a hindrance... but Jake just needs to grow super huge and pick up the underwater duo and toss 'em... at least in the scenarios in Khazan and on the beach.
In the treedome, however, Spongebob has knowledge of Sandy's inventions and *may* be able to find and use one of them, possibly to take on Finn and Jake, but I'd still give major odds to the magic dog and totally mathematical human.
