A novelty device having a vibrating mechanism that is disposed at least partially within a housing. The vibrating mechanism causes the housing to vibrate when activated. A plurality of elongated elastomeric protrusions are provided that extend outwardly from the housing. The elastomeric protrusions undulate when the housing is vibrated by the vibrating mechanism. The housing can be shaped as a character having a head section. The elastomeric protrusions can be placed on the head section of the character so that the protrusions have the appearance of hair. When the vibrating mechanism is activated, the protrusions undulate wildly, thereby causing the character's hair to appear to be alive.
