Prismatic Frog

Prismatic frog is all colors.
When Prismatic Frog enters the battlefield, create one mana of any color.
Frogs of the Fooman Forest have a knack for making the mana. At the end of the tadpole stage, they undergo metamorphosis in which its body makes a sudden transition into the adult form. This metamorphosis typically lasts only 24 hours- unless it is a slime year.
