If there was a Tropical Freeze stage, it would've been based on World 5, anyway.
Jungle Hijinxs is Donkey Kong and Diddy Kong's home stage in Smash 4 Wii U. This stage is based on Donkey Kong Country Returns, and actually features a brand-new mechanic exclusive to this stage: You can use barrel cannons to fight on multiple planes! Woah, Sakurai must really love the Donkey Kong Country series to give it a completely unique mechanic!
...Oh wait, it's a jungle stage, so he still hates it.
Also, this stage has a whopping four versions of DK Island swing. That's more than any other stage in the game!
== Tournament Legality == With this one, I have no idea. I'm sure it's gonna be banned in most tournaments because it's different and different = bad, but who knows? It could be a pretty fun competitive stage. Only time will tell.
