The Crying Child seems to be "pixelated" with blocky features. Like from the minigames in the second and third game of the core series, they have black eyes streaming with grey tears. They also have the same crying animation. They're abilities are Power Song - A white attack that boosts the team's attack for a limited time.
Armor Song - A white attack that boosts the team's defense for a limited time.
Gift Boxes - A yellow attack that grants the team an extra life and revives them at full health
