come on, i expected a man eating a plant when i clicked on this page

Come to think of it, you can also KILL the Man-Eating Plant if you use the Sponge soaked with Developer on it, which is similarly obscure. There's no unique sprite for that though, the plant is just missing and it's only the pot left, so probably doesn't need a revision just for an isolated pot tile.

Fun fact! Using the Glass Jar on the Pool will fill it with radioactive water, which can be poured onto the Man-Eating Plant to make it get tall enough to reach the ceiling. That's required to beat the game, but what most people DON'T know is that you can also use the Sponge and soak it with Pool Water. Using that on the Man-Eating Plant will make it grow only partially to an otherwise unseen intermediary state, requiring you to make a second trip if using the Sponge. There's basically no reason to do this, since the Glass Jar is typically gotten much sooner than the Sponge and is just more intuitive (as well as only requiring one trip), making the Sponge method fairly obscure.

I submitted a revision of the sheet with the intermediary sprites already, but I also thought I may as well share some fun obscure trivia. The Sponge trick works on every version of the game, by the way.

BURP!
