TED-Ed: Daniel Finkel: Can you solve the cuddly duddly fuddly wuddly riddle?

The video tutorial explains the process of adopting a creature from the Wuddly species, focusing on the egg fusion process. It describes how different colored eggs combine to form new colors, ultimately determining the type of creature that hatches. The tutorial guides viewers on how to choose the right egg to ensure a Cuddly hatches, emphasizing the importance of parity in the egg fusion process. By adding a blue egg to the incubator, viewers can ensure the final egg is blue, resulting in a Cuddly.
