    At least this are authentic creatures with authentic names, what the hell was that of having names as Vile and Torchwing repeating one time and other and another no sense

    The slime quality is great! The monsters are beautiful! Such a great toy, fun to build, fun to play with. Suitable for girls and boys. Goes well with MOTU He-man series as well.

    I cannot express how much I love these toys! The slime is a bit of a pain to remove (it is way stickier than Breakout Beast series 1 & 2 slime) but the creatures are absolutely worth it! The interchangeable parts make for endless customizing fun! I love mixing the Creatures and Beasts with the baby dragons from Game of Thrones. I've recommended Crystal Creatures to so many people. They are some of the coolest products Mattel has ever made!

    It was nice to put together but a pain to get the slime out of the small areas of the toys I'm not a fan of slime so it was gross for me to have to do that, it be nice if it was already separated. Other then that it was great
