As part of its ongoing efforts to promote every single Pokémon out there, The Pokémon Company has shared special content dedicated to Gothita and Smoochum:
Gothita: Though they’re still only babies, there’s psychic power stored in their ribbonlike feelers, and sometimes they use that power to fight. Even when nobody seems to be around, Gothita can still be heard making a muted cry. Many believe it’s speaking to something only it can see.
Smoochum: If its face gets even slightly dirty, Smoochum will bathe immediately. But if its body gets dirty, Smoochum doesn’t really seem to care. This is a very curious Pokémon. Smoochum decides what it likes and dislikes by touching things with its lips.
