Santa Monkey is a special agent that costs $150 Monkey Money. He flies around the screen randomly on his sleigh, throwing gift boxes onto the path. When Bloons get to the gift boxes, they get trapped inside (the boxes can hold one of any type of non-MOAB-class bloon). Then the boxes can be destroyed with ordinary attacks. If you use Santa Monkey in 50 games, he becomes Santa Monkey Pro. Santa Monkey Pro has bigger gift boxes that can hold two bloons each.
