Sliggoo is a Dragon-type Pokémon introduced in Generation VI. It evolves from Goomy starting at level 40 and evolves into Goodra starting at level 50 when leveled up during rain (or fog in Generation VII) in the overworld. Rain instigated by Rain Dance, Drizzle, or Primordial Sea will not trigger this evolution. Take a look below for 23 amazing and fascinating facts about Sliggoo.
