"Boasting the Sap Sipper and Grass Pelt abilities, Skiddo first appeared in Omega Ruby and Alpha Sapphire, followed by Sun and Moon, and then returned in all the newer Nintendo Switch games."

Skiddo and Gogoat first appeared in Pokemon X and Pokemon Y, not Omega Ruby & Alpha Sapphire. They also only appear in Pokemon Scarlet and Violet on the Switch.
