At first glance I didn't care for these things. But they actually go well with the Masters o the Universe line. But $10 is too much $5 seem closer to what you get. Usually around 15-20 pieces. The pieces covered in slime was annoying, and a big turn off. But for those that like slime, it's an extra value that you may like. I had to get a tooth pick to dig out the slime that gets settled in the small gaps of the pieces. The larger soft plastic pieces are usually bent out o shape due to being crammed inside the plastic bags and stuffed inside the tight fitted eggs. I decided to buy a few eggs because they were on sell for $6. Plus my Niece loves Slime for some reason. No matter How I feel about it I Do believe that a lot of kids will love these mysterious creatures, and the slime that they are buried in.
