How to unlock the Plantastic achievement in Thimbleweed Park - Definitive Guide
When you gain control of Delores in the Part 3, grab the math trophy from her bedroom. Advance in the game until Part 6, where you will have access to steal the key to enter the abandoned factory.
In the factory you will find a big leaking tank of radioactive green liquid (is next to the number 3 clock). Use the trophy with it to fill it with the waste, then get to the Quickie Pal and feed the plant to unlock.
Maybe do this before using the radioactive waste at the trailhead.
This achievement can unlocks without the popping notification on screen, so check the achievements list to be sure if is unlocked or not.
This can only be unlocked on Hard.
Once you gain control of Delores in Part Three (not during her flashback), pick up the math trophy from her bedroom. Play through the game until you get access to the abandoned factory in Part Seven. Near time clock 3 you'll find a leaking canister of radioactive waste. Use the trophy with it to fill it with waste, then get to the Quickie Pal.
Enter the Quickie Pal and use the trophy filled with radioactive waste on the plant to unlock this trophy. I THINK you need to do this before you use the radioactive waste at the trailhead, but I'm not entirely certain.
MISSABLE – Chapter 6
MUST BE DONE ON HARD MODE
Once you gain access to the factory you will find a canister leaking toxic sludge. Use the trophy found in Delores’s room and scoop up some sludge and feed it to the plant in the convenience store.
You need to water a flower in a store with radioactive liquid collected in a cup.
