Nope. That is not a typo. These are living beach balls that somewhat resemble bees.
In order from left to right, top to bottom, they are:
Bonka - The smartest one, albeit slow and lazy. He is often the one who's thrown around the most.
Akka - The angriest one, demanding attention. He is very trigger-happy and will frequently ram into objects or people.
Bakka - The scaredy-cat. He often flies away from even the slightest of threats, crying. The other Beech Balls comfort him frequently.
Rakka - The happiest one and optimistic to a fault. He is the de facto leader as he's very extroverted.
They are unable to feel blunt force pain and those they frequently offer themselves to participate in various games - their favorite being a special variation of dodgeball no one seems to understand...
