Can someone please give me a quick rundown on Transformers? My 3.5 yo bought a Bumblebee toy today (first purchase with his own money!). He's played with Bumblebee at a couple places and is OBSESSED with the toy but has never actually seen anything Transformers. I thought they were just movies but I guess they are shows? Are any appropriate for a 3.5 year old that feature Bumblebee that I can stream? I googled it but it seems like there's a lot of transformer stuff out there, haha. Help!
