Sab tribulation mode world 2 zone 1
There are 2 workarounds to almost all of your problems, after killing the tree stump in front of that checkpoint there are hillbillies, to the side of that mountain you can jump down the ledges and climb up a waterfall. Use a bomb to reveal a secret room that is very dark with many hillbillies, once you reach the end of the cave you end at the end of the “frogger” part and you take a simple wooden log to the store. The mushroom part you are referring to, you don’t have to do it at all if u travel the logs on the waterfall, b4 the last hilltop (4th one) and the 2nd to last (3rd) there is a log that travels fast all the time, at the end of that there is a secret bear cave, if you climb it to the top you end right at the checkpoint before the final boss.
