Based on a Serbian children's song about bumblebees trying to bring the order to the meadow. Bumbar means bumblebee in Serbian.

Players organize their hand to create pairs, triples or quadruples of animals to score points. When player has only pairs, triples or quadruples, and they are adjacent, they can end the round, and everybody scores. First to 21 points wins the game.

The game is played completely from hand, and does not need a table or playing surface, making it perfect for travel or waiting in lines at conventions.
