Jungle Hijinxs
No rhyme, no alliteration, no pun... and I believe the spelling is incorrect, too! (Many references suggest 'hijinks' — and a 'k' would be more DK-riffic, anyway!)
Why on earth did Rare choose this name for DK's home turf?
It has been mentioned here that this level used to be called 'Jungle Japes' prior to the game's release — a name DK64 fans will recognise.
Further use of 'Jungle Japes' as the level name, from Mexican 'Club Nintendo' magazine:
This long-abandoned name is a much more catchy and fitting one, I think.
Why do you think 'Jungle Hijinxs' was chosen for the name, rather than Jungle Japes?
