Fennel's Munna was first seen by
Ash Ketchum at the Sanyo City Pokémon Center when
Fennel came rushing in with her Munna and was able to heal Iris's Kibago. Munna ate
Iris' Axew's dream which was a happy dream and it turned into a pink smoke cloud.
Fennel's Munna used Pyschic to damage the Future Energy mecha at the Dream Site Ruins.
