The Toughnuts like to think they're unbreakable.  They aren't, but you're going to have to hit them a bit harder if you want them to go down.
 
The set consists of 1x Snodgrease, 1x Cheesehawk, 1x Granspike and 3x flying bases.  The set consists of small pieces that may present a choking hazard and is therefore unsuitable for children under the age of 8 years.
