207.Boiling Point

Locked in the game until all 200 levels of chapters 1–20 are solved. Then the bonus chapter opens, and its steam parts join the sandbox.

Goal: Ring the bell with the tennis ball from the top shelf, then blow the whistle, then pop the balloons. The boiler bursts if it stays full for 3 seconds.

A boiler stands bottom left, a tennis ball sits on a very long shelf, and a bell, a powder keg and two balloons wait on the right. Bell, then whistle, then balloons, and the boiler bursts if it stays full for three seconds.
