Two planets collide, forming one world. Two distinct skull-faced societies are split down the middle. One side is wild and stone age, named Retrovia. The other side is systematic and ultra-futuristic, named Futerra. Retrovia and Futerra compete in various wacky challenges in the arena known as the Chrome Dome for Skulldallion medals. Whichever side of Craniacs wins the most Skulldallions after one year's time, gets to rule the entire world! From the creators Joke Simko and Ira Friedman comes the Craniacs Series 3 Skullblam Blaster Box! Plus, there are exclusive Blaster Box FOAMOs to find! Every Blaster Box comes with 7 packs. Each pack contains 6 base cards along with 1 sticker or chase card.
