Glowdrop
From Bulbapedia, the community-driven Pokémon encyclopedia.
Glowdrops are items that appear in Pokémon Rumble Blast. They are used for healing purposes and are also an item that Cobalion wishes to steal.
Uses
Glowdrops appear in every town in the game. They are located in the fountain, which is in the center of each town. By touching it, all the Pokémon the player has collected has their HP restored. These are for unlimited use.
Impact on story
In Toy Town at the beginning of the game, a Lillipup accuses a Pawniard of stealing the towns Glowdrops when they go missing.
