Monster Kid is a young character in the game Undertale. This game character is a harmless and energetic yellow monster. Monster Kid is a small armless kid with "spikes" on his head. He is a big Undyne fan and dreams of seeing her and becoming like her. He is very inattentive, so he often stumbles and falls. Perhaps this is due to the lack of hands to maintain balance.
