The Crash Bandicoot N. Sane trilogy seems to have a thing for small gameplay clips. Just like the "Un-bearable Transformation" video, this glimpse at the updated Polar character is only a few seconds long, but it definitely conveys the point. Here's the trailer:
Polar initially made his debut in Crash Bandicoot 2: Cortex Strikes Back as a rideable mount, not unlike how Yoshii used to be for Mario. The character made a brief appearance in Crash Bandicoot 3: Warped in an in-game CG moment before finally being a playable character again in Crash Team Racing.
Crash Bandicoot: N. Sane Trilogy releases on PS4 on June 30th, 2017.
