The Safety Hedgehogs, also known as the Hedgehog Family are two hedgehogs who appeared in adverts for THINK! road safety from 1997 to 2008. The adverts were shown to encourage children to follow the Green Cross Code when crossing the road. The adverts focused on two young hedgehogs: a large one who represented an older child and a small one who represented a younger child. In the adverts, the younger hedgehog would attempt to cross the road, only to be stopped by the older hedgehog who encouraged his brother to Stop, Look and Listen out for cars before crossing the road. Each advert would see the older hedgehog singing about road safety in the tune to well known songs, e.g. King of the Road in a 1998-2003 advert, Stayin' Alive in a 2001-2002 advert and Ain't Got No Home in their newer ads from 2003-2008.
The Safety Hedgehogs appear in All Star Smashers as a Support Spirit, as an Ace class, where you must fight Pete the Cheerful Bus Driver at Radstock Museum as a character of your choosing to obtain them. When fighting Pete, stage hazards will appear more frequently, a tidal wave of furries will appear, and Pete will be distracted by items.
