The Goomy Evolution Controversy is a confusing system of ideas that state whether or not Goomy should be evolved. One main belief is that Goomy shouldn't be evolved because it will take Goomy out of its pure form. The other is that Goomy can be evolved because Sliggoo and Goodra are still Goomy. This diagram shows the beliefs as of now:

 Those who believe Goomy should not be evolved       Those who believe Goomy can be evolved


                Those who believe that Goomy may only be evolved if another Goomy is owned and is kept as a Goomy

This system has caused no official split in The Church of Goomy. This matter also has not been resolved in The Ten Goomandments.
