These toothpaste heads by Spread Heads are a fun way to promote good dental hygiene among children.
The visual idea of an animated dog or cat spewing out a bright neon coloured gel onto a toothbrush might have varying degrees of appeal, and like almost every other funny product, the opportunity for gross variants is wide open (i.e: alternative coloured toothpaste or less politically correct heads).
Implications - Children need some form of entertainment while completing monotonous everyday tasks. Products that contain an element of whimsy will appeal to parents shopping for their kids. Companies could appeal to the younger market as well as the parental one through integrating playful elements into their items.
