1,1 empty state

2,1-3,1 absorbing enemy

4,1 filled state

5,1-6,1 shooting out enemy

the absorbing enemy animation plays the exact moment an enemy is successfully captured by the suction gun

the 'absorbing enemy' animation seamlessly flows into 'filled state', and 'shooting out enemy' flows into 'empty state'

other than that, the backpack has no other animations. every other player animation uses 'empty state' or 'filled state'
