Upon logging into your Pokémon Global Link account with a linked game you should be presented with a Personal Notification banner saying "Fennel's Munna has appeared as a Thank-You Gift from the PGL"
Personal Notification Image.
The Munna is based on Fennel's Munna from Pokémon Black/White and comes in a Dream Ball and has its Hidden Ability.
Competitive Pokémon Note
I can't find anywhere that its IV's are locked so it should be able to be Soft-Reset for IV's if you wanted to have IV spread for competitive battling.
