Storyline
It's almost Halloween, and for best friends Marshall, Gilbert and Amy, that means it's been a year since they returned their mummy pal Harold back to his eternal resting place with his girlfriend, who they’ve affectionately named Rose. When an evil mummy from Harold and Rose’s past is unexpectedly awakened and out for revenge, it is up to our three friends to use their skills to save the day once again. Friendships are tested as our kids work together to keep their ancient pals safe, defeat the evil mummy, and get back in time to attend Amy’s dad’s Hallowedding.
