After defeating Octo, you wind up in a hot spot.
Tik and Tok are here to sell you things, and Tik is going to help you out by joining you. If you're playing with fighting game combos, that's a lot more moves to learn so check out the practice menu.
The reason Tik joins you is so he can help you and you can help him and Tok get some green gems. Don't forget to grab the ones at the end of this nook. There is a sound effect but no other indication you got them, but you can check in the menu.
Don't forget to equip any new belts you get. Speaking of that, when you see the giant boulder, go up and grab the Orange Belts, just be careful not to get hit.
These daggers make the boss easy so don't forget to grab them.
Sensei comes back and awards you with Green Belts.
Soon after that you'll run into Chilly. He'll keep spitting out enemies so kill him first. Once you KO him he'll let you past.
There's an elevator here. The ever adventerous Jellybean must have gone up, so up you go. Tok joins you.
