The first thing is that bunnies hop. and this video shows that by dragging feet behind to give that effect. he also used a mixture between ones and twos, ones mostly on the ground and twos when the bunny is in the air. i believe it makes the character feel more lifelike. and showing the effect of gravity by slowing it in the air.
there is alot of fluidity in this animation, while i was going through it i noticed the amount of good posing. even in the breakdowns and inbetweens. This bunny uses alot of construction mainly consisting of circles to give it a more cutesy look.
