It is one of three collectable characters that are fun companions to the Gro-egg. The Gro-egg Shells maintain all of the Gro-egg’s current features including its important night light and temperature reading functions. Mikey the monkey makes the Gro-egg more decorative and visually appealing for both children and adults, whilst maintaining its practical safety features that so many parents have come to rely upon to ensure their children have a safe night’s sleep.
