The Ice-Cream is two scoops of fail...
As for the Bear, it looks relatively decent, but it doesn't have the stats to back itself up, that and mono-type Ice is bad. In a lot of ways the Bear is just like Ursaring; poor stats, bad mono-type, and cool looking. Honestly neither of the two are worth using.
As for the Pokemon of this generation, I feel that the ideas were quite solid (Trash Bag & Ice Cream specifically) but they ruined the Pokemon by drawing them. I had high hopes for the Trash Bag, but it ended up being trash.
