Retro fridays and 3 ninjas

I'm talking about the movie series staring colt,rocky and tum tum. I have seen all 4 but for some reason I only remember the 1st and the last one. I'm sure if I watch them I'll get strong deja vu. I like how 90's these movies feel. Especially the boys room in the first movie. When I was little I always wanted to have a sleep over with pizza and soda and NES and watch this movie among with the wizard.
