Example: An emperor penguin that has the ability to keep its breath underwater and swim faster, able to explore deep under water caverns and withstand freezing cold temperatures.
Or... a snow plow vehicle.
Yeah... sorry to say but this pales in comparison to Banjo Kazooie. Even without comparisons I think it's pretty meh. I wanted it to be good but, just no. The transformations are boring and frankly pointless. I'm sure Yooka could have used his huge, blocky, shovel shaped head instead of needing to be transformed into a snow plow.
