Shade

Shade is an evil creature who was trapped in a tombstone after a battle with a wizard.
When you meet him he awakes from a long slumber and tells you he wants to regain his power so that he can repent and do good deeds.

To regain his power, he needs Shade Remains.
Shade remains are obtained by trading in bugs and fish.

What happens when you give him 10 Shade Remains?

Shade tells you he's really still evil and that he will rule the world once again. Then he uses his magic to get rid of all the weeds and bad mushrooms in the game as a test of his power. But this takes up so much power that he cannot resurrect. Thus he falls back into slumber.

After a couple of days, the ritual begins again.
