Softlocks

Banjo Tooie known softlocks:

Mayahem Temple Puzzle http://www.twitch.tv/red_jinjo/c/3383233

Mayahem Temple randomly? http://www.twitch.tv/alpha_que_up/c/4330548

Any warp pad if you land in the right spot

Cactus of strength http://www.twitch.tv/alpha_que_up/c/5414005 (why does this shit always happen to you alpha lmao)

Quality Control if you collect the jiggy in the cutscene

Any clockwork warp if you do so on the last possible frame.

Most? loading zones will softlock you if you shoot a clockwork while sliding into the loading zone (likely only possible on icy side hailfire peaks due to the environment).

Sometimes if you use banjo solo moves while talking to jamjars, the game does some glitchy animations and can softlock the game.

Tower of Tragedy - With some unknown timing, if you skip a question at the end of a round, it loops Grunty's text. If she flies away before it loops, the game softlocks

Terrydactyland (could work in other areas too) - "softlock" clockwork warp on one of the little tunnels by the split up pads, and the game will give control to banjo. If you die, you get 2 banjos. If you then try to switch to kazooie, the game softlocks.

Cronikeys softlocked inside the mountain in TDL once by fluttering and beak busting on the surface of the water, but it could have been an emu crash.

Grunty Industries - Sometimes you will softlock when you jump down to jamjars to learn claw clamber if banjo slides too far.

Jolly Roger's Lagoon - If you poop an egg at tiptup and hatch the egg at the same time, the game will softlock https://www.youtube.com/watch?v=fOKjEbhR4g0
