Now that you met Tom, he asks you to gather twelve water lilies for Goldberry.
Tom will hop, skip, and jump around on his own little path so sort of follow
him. Many of the lilies will be within sight from where Tom goes so keep an
eye out for them. Beware because all of the lilies are being guarded by
spiders. Try your hardest not to lose sight of Tom because it's pretty hard to
find him again. If you can't find anymore lilies where Tom walks then you'll
have to go off searching. If you lose Tom then search for him near the stream.
Once you find 12 lilies then talk to Tom and he'll bring you to his house.
