Now that you have it go back and walk into the open room walk back out and you can redo it over and over. 2nd the find the coin bonus game the first time the coin is at the top of the barrels but after that it is on the ground. You can do it over and over in one game how ever many times you want. Now to the lives get Rambi after you do the bonus coin game his box comes back.

On the first level of Krem Quay, go to the second spinning barrel after the first Kloak. Shoot directly up, and if you look closely you can hear another barrel shoot with a puff of white air,which will fire you back down. This is actually a warp barrel that was disabled by RARE in the BETA version of Diddy's Kong Quest!

In Pirate Panic, go into K.Rool's cabin (don't collect the balloon) and then leave.
Jump over the first two bananas, then collect the next bunch on top of the barrels. Still avoiding the first pair of bananas, return to the cabin and grab the balloon.
Repeat step 2 then return to the cabin, still avoiding the first two bananas. You'll get a floating Kremcoin in the air. Grab it to automatically get all the Kremkoins.

This is a glitch that can usually everytime erase EVERY SINGLE FILE, SO DO NOT DO THIS GLITCH UNLESS YOU DO NOT CARE ABOUT ANY FILE! To do it, go to Castle Crush with only Diddy. Now, grab the first DK Barrel in the level, now drop it and pick it up again, and if done right, it will break and you will be holding it in the air. Now throw the DK Barrel that you can't see, and Diddy will turn into a weird thing such as Klubba!
