So, here is what happened.
LEVEL 7293
My frog was charged up. I needed 1 rainbow rapid to collect, and a rainbow twist was blocking its path but could be destroyed if the frog landed near it.
A candy bomb was at 1. I use my frog and destroy the chained rainbow twist. Candy bomb counts to 0, but the rainbow dispenser has an open path to its box
So the dispenser should have fired its rainbow to the box. be collected, and the level be completed, right? NOPE. Because of the game code's order of operations, the bomb explodes and I had to cough up 10 gold bars, just to then sit and watch the dispenser let loose the rainbow and complete the level. I had to pay 10 gold to win.
WHY?
