 * Guppy's Hair Ball also creates blue flies when dealing damage which is a feature unique to challenges where Isaac is blindfolded, making it considerably stronger than normal.
 * Guppy's Hair Ball is very difficult to control. It would be wise to spend the first few attempts at the challenge by practicing with it before a real attempt at completing the challenge is made.
