RTABC Guide/WF 100 Coins
This is a guide for how to beat the 100 coin star for Whomp's Fortress with 0 A presses in an RTABC run. Note that this is usually done with the red coin star in a full game run.
Method
Start by plucking the Piranha Plant near the start and grab the line of 5 coins near the Bomps. After moving across the moving platforms and teleporting, get on top of a Whomp (which will also reward you with a coin) so you can get on the elevator. Next, move to the floating platforms and collect the two red coins as well as the coin arrow and the circle of coins before heading to the red coin on top of the Thwomp. Teleport once more to the circling bridge where you will collect the fourth red coin. Kill two Piranha Plants and grab the red coins they're guarding as well as the line of coins near the BAtW star before carfully slide kicking onto the platform directly above the SitWB star to collect the ring of eight coins there. Fall down and smash the little cork box before moving ahead. You will soon reach the shallow water containing some more coins as well as a red coin on a slippery slope. Carefully frame walk and mash the pause button to slowly but surely grab the seventh red coin. By now you should have 75 coins. Grab a circle of eight coins in the water, the line of five coins near the start, and collect the final red coin on top of the Bomp. The red coin star will spawn, and in a full game run we will be collecting the star after the 100 coin star, but for the purposes of this guide we'll ignore it. With 10 coins to go, collect one last circle of 8 coins before smashing the final little cork box. Collect at least two of the three coins that spawn and the 100 coin star will appear before you. Grab your prize and that's it!
