Mistral's trying not to giggle himself. "I'm not sure... get away from the trees?" He knows he could use his Bell to get the Hiploop's attention, but he's a little reluctant to do so right away. It just looks like it's having fun.

Lono waddles up with one last Boe that the Hiploop knocked out of a tree, and Mistral decides to let the pet play until he's back from dropping the load off. Then he'll give in and use his Bell to get the Hiploop to stop attacking trees so they can continue up the mountain.
