Well it's very nice to meet you Fueco, and Miraidon too.

[He's nodding as Juliana introduced her Pokemon to him. His Meltan too will will wave its little arm in greeting.

Mimmeo will silently stare at both Juliana and Willow for a moment before it lets out a screech! Not out or pain or frustration. It somehow sounded happy.]

So far it's been a rather friendly Pokemon. Perhaps it's not a wild one? But I don't see any other trainers nearby aside from us.
