I can confirm, however, they are just as slimy as they look. No, I wasn't quite brave enough to touch them, but I was with a child who was (Don't worry: She was also old enough to understand "Don't stick your fingers in your mouth afterward"). The slime pulled away in long strands, much to her delight.
