About
When nighttime reading causes monsters to lurk under his bed, Milo signs his friend for advice. From her window, Mel signs for Milo to use his monster hands to scare the monster away by making shadows that roar, chomp, and laugh. Only when the duo uses their monster hands simultaneously does the monster finally disappear!
