lightning master

Today I visited Dean during school just before his naptime.  He was quietly playing with some magnet toys, and he kept referring to "lightning master". 

Finally, I asked him, "What is 'lightning master'?"  He said, "Lightning Master is a movie I made up.  It's like 'Peter Pan'.  There's a guy NAMED 'Lightning Master' IN it." (emphasis his). 
Brilliant.
