To begin, Bare-handed Grunt doez the only thing he can do and stepz on the Black One-Time Switch (BOTS).
Looking around, he seez another BOTS he can reach, and stepz on it.
Now he is able to pick up a Yo-Yo (Toy #1) and handz it to an enemy Grunt to distract him so he can get the Shovel (Tool #1) , quickly slipping back past Sword before he getz angry at having nothing left but a string.
Then he usez his Tool to uncover a CheckPoint Switch (CPS) and satisfiez his own CPS , then movez on to uncover yet another CPS .
There is a Tool (Tool #2) on the last one (that doesn't match the requirementz) that he pickz up and smashez everything nearby (being careful not to step on the BOTS so tantalizingly near, nor does he get greedy and grab a Coin) (yet).
Down to break the Giant Cupcake


revealing a Coin on a BOTS .

(Yes, he may take the Coin ... forced to step on the in the process.)
Then he satisfiez the CPS near the King's Fortress, clearing the way to the Warpstone CPS .
Now, he can step on the BOTS and satisfy the CPS by grabbing the Coin .
That done, he discoverz more work to be done with the Gauntletz!
Now he getz the Boomerang (Tool #3), and satisfiez the CPS and findz a safe place to throw away that bent piece of wood ... four times(!) ... creating two Goo Puddlez .
He pocketz the Warp letter and goes back to get the Springz (Tool #4) he uncovered when he had the Gauntletz.
The rest is "a piece of cake"!
Once through the Spikez maze to the Warpstone, all you need to do is take it to the King' Fortress.
