6. Set the temperature to 25 degrees
7. Head up to the attic and grab the rusted pig

once you find the Brook Chalice seeds in the attic you can begin to grow the Brook Chalice by doing the following:

1. fill a pot with soil at one of the plant worktables
2. add an Brook Chalice seed to the pot
3. water the seed
4. take the seedling to the bathroom and place it in the designated spot in the bath tub
5. if you have not done so already, repair the pipes that lead into the heater along the wall with the pieces of pipe lying around the room (this will get you the Who needs a plumber? achievement)
6. set the temperature on the heater to 25
7. head back into the attic and find the rusty pig on a table right near the top of the stairs and then take this rusty pig into the bathroom and place it into the bath tub beside the seedling
8. turn on the bath (achievement unlocks when plant is done growing)

if you make an oops by filling the bathtub at the wrong temperature, simply drain out the bath water.. correctly set it up as described above.. then turn the bath water on again
