Into a thick Ziploc freezer bag we put green glitter (scabs) - hair gel (blood) - wiggly eyes (monster eyes) - Easter grass (veins) and baby oil for extra slipperiness.
Oh yeah and don't forget the monster teeth!
(Beads from an old necklace)
It proved to be a very popular sensory bag!
Of course we taped it shut as well - just in case :)
