Shady: Bears Unblocked
This version is not a platformer at all, but a fast-paced . Its description on Unblocked Games 67 states, "Shady Bears is a unique and highly addictive, unblocked arcade defense game with a simple but brilliant mechanic". The gameplay is centered around a tree that you must protect from parachuting bears. You defend your tree's honey by clicking and holding on the trunk to grow branches that can intercept and knock away the falling bears before they reach your tree. This one is all about quick reflexes and high scores. It's less common but is sometimes what people find when searching for an "unblocked" version.
