A demo build of the game shows that Frogger would've had a lot more animations, including Frogger bouncing, doing a mid-air flip, and extra death animation, hopping to his left and right, doing a cartwheel, a "leapfrog" animation, panting, an alternate slipping animation with one slipping to the left and one to the right, a drowning animation, doing a super hop, two idle animations, kicking upwards while doing a handstand, and doing a "superstart."

The sinking and mid-air flip animations would later be used in the sequel.
