Just yesterday my four-year-old granddaughter and a three-year-old boy who is a friend of the family were watching Wild Krats. The little boy had never seen it before and was really enjoying it but couldn't for the life of him figure out how those guys could turn into animals. So, my granddaughter was using all of her four-year-old wisdom and logic to explain it to him. That was a fun conversation to listen in on. He was the most excited when he found out they could even turn into butterflies.
