--- Lily ---
When Lily and Hedera got themselves moving it was easy to clear the room. With Lily's shadow control she didn't even need to swim down to the bottom of the pool. If they'd been called out for cheating Lily would've swum down… but Trapmaster clearly didn't bother being too strict in this room. It was more for getting clean clearly.
The next room had an obvious solution that required a fair bit of effort to implement. Inside was a big wall with four colourful buttons set in the cardinal directions. The big sign saying 'match the pattern' was almost unnecessary. When you got close to the wall, the lights would flash in sequence, playing a unique tune for each. The top button was red, then going around clockwise you had blue, green, and yellow.
