One of the coolest brand of dolls out there are part of the Monster High gang. A fashion doll line launched by Mattel in 2010, the toy was a huge hit. The characters are inspired by monster movies, science fiction, and other creatures like Frankenstein, sea monsters, skeletons and more. The animated series soon followed with its release on YouTube. Mattel is at it again in 2021 with a new series and live action movie, gearing up to air on Nickelodeon. If you’re a freak for the Monster High characters, you’ll love to color them. Grab your crayons and have a spooky day! If you love these you might also love some Halloween coloring pages, or Nightmare before Christmas. Or maybe you want more doll coloring pages, like American Girl, Littlest Pet Shop, LOL Dolls, My Little Pony, and even Paper Dolls.
