I forget what it's called but it makes mutant plants.

Step 1- Make mutant plant and raise it three levels
Step 2- Hire Maid.

The maid will feed th plant garbage and make it unhungry so put garbage cans near it.

Step 3- try to get the maid near the plant.

The mutant plant should eat her.

A pop-up will say boo-hoo the maid died may she rest in peace blah blah blah.

Step 4- Hire another maid.

When she shows up she will be a ghost, Thus being able to walk through walls and clean your house faster, making the pay lower!:)
