If you want to jump further than the average ape, for obvious reasons- Just press B after you jump at its peak while holding the direction you want to go. Some kongs may not go as far as other kongs though. Heres my grading scale on how this small little hint works:
DK:5/10 He just does a karate chop, so not that helpfull...
Diddy:8/10 He spins like tiny, but it ends soon. Helpfull though.
Lanky:8/10 He spins his arms around him, which somehow is helpfull
Tiny:2/10 This teqniuqe absolutly sucks on her. Just do her spin thing with A.
