Nigel B. Whistlebottom

Nigel B. Whistlebottoms are cops in the Smithsnorian Museum in the game Wario: Master of Disguise. They are very common, and when they spot Wario, they blow a whistle and alert other cops and tell them to come in the room. Other cops (Officer Kicksworth, Sergeant Houndstooth and Dave the police dog) come in the room and try to defeat Wario. He will summon more enemies each time as the player spends more time in the level. Nigels are invincible; however, they can be knocked out by jumping on their head a few times. After being knocked out, they are stunned for a few seconds before they can fight again. They use baseball bats to attack.
