It’s the latest of the Pokémon Snapchat filters!
Tying in with Pokémon’s 21st anniversary, the final on three Snapchat filters has finally gone live on Snapchat. This filter is based on Squirtle and features a water animation as you open your mouth. This follows on from Bulbasaur’s back in February and Charmander’s back in April. It is currently unclear for how long the filter will be available.
