IPBJ (Ice Palace Bomb Jump)
IPBJ stands for Ice Palace Bomb Jump. It refers to a particularly useful bomb jump performed on the B2 level of Ice Palace. The IPBJ tends to be referred to specifically in many cases because it’s not only easier to learn and execute than most bomb jumps, but saves a significant amount of time when traversing Ice Palace, such that not taking the time to learn the IPBJ could put you at a significant disadvantage in a race setting.
