Alright, here's the full solution.
1. Flash the barrel and Reflash it on the red button.
2. Collect the two Flash charges in the next area. Get four coins and Flash the fifth.
3. Carefully, to avoid getting zapped, Reflash the coin on the center right square of the rectangular area where the ZapBots are circling.
4. One ZapBot will head down and begin following a new path, while the other will stay in its original area. When the one that stays is in the west of its area, head to a square several spots below the coin (but not in the spring). When the ZapBot moves north of the coin, it will fire a laser in your direction. Because of ZapBot logic, the laser will keep firing for a second after it moves, and as such, the line of barrels will be destroyed.
5. Step on a faint Pow charger and destroy the ZapBot that just destroyed the barrels, the one that goes near the coin. Don’t collect the coin, though.
6. When the remaining ZapBot is out of the way (far enough north), put a Floing bubble in front of the spring facing north and Blink into it. As fast as you can, collect the other two Pow chargers, head to MooseJaw, and click through the dialog, stopping after you’ve clicked on the all-caps response. Once the Floing bubble bursts and you’re sprung downward with the final coin, finish the dialog. A rainbow key will appear by MooseJaw.
7. Head west. When the ZapBot is south of the red gates, Pow the barrel on the red button, changing its path.
8. Head farther west, then south. Pow the Fireflower.
9. This is easily the most devious part of the level. First of all, here’s what you need to understand about crab logic: when you get within two squares of them, they will go into a “panic mode”, running away from you, and they will stay in that panic mode until they get at least four squares away from you. Cast the Floing spell two squares to the right and one square down from the indigo teleporter. Blink onto the square below the Floing bubble so the Blink spell gets trapped in the bubble. Before the bubble bursts, collect the nine Brrs, use two on the water near the crab, stand as close to the crab as you can (above the west ice float) and wait. When the bubble bursts, the crab will still be in “panic mode”, causing him to run left.
10. Chase the crab into the water west of it and use four Brrs to press the purple button and return. Step through the spring and, watching out for the ZapBot, collect MooseJaw’s rainbow key.
11. Use two Brrs to get the key behind the purple FlipBridge.
12. Still watching out for the ZapBot, make your way to the square just east of Doondilf. When the ZapBot is about to move north of you, freeze it. Talk to Doondilf, wait through the countdown, and you will bounce against the frozen ZapBot. Before talking to Guggenheimer, make your way to safety and wait for the ice to melt and for the ZapBot to head east and north. (Note that the ZapBots have a very high shooting range and as such, you shouldn’t get in a straight line with them at all.)
13. Talk to Guggenheimer and get the rainbow key from him. You may have to wait again for the ZapBot.
14. Use the four rainbow keys to get the star.
Any thoughts on the difficulty?
