Having played with everyone a bit since then, he seems to have opened up a bit. He has also eaten a lot of curry, so he may have fattened up a bit.
And it seems he is trying to break into the place where Russtie the Greedent is making curry and take away the her berries.
Is it because of the tribe involved that she doesn't want to share berries?

Anyway, the female Greedent is named Russtie(ラスティ), who is Quiet and Mischievous. I met her when I was level 4 in Route1 and she is now level 83. She is a very durable, and in the last tournament scene, she was so strong that she alone defeats all of foes.
I had not expected the Greedent to be so strong.
