Fisher Price ‘04 Peek a Boo Blocks Train, + 5 Little People + 1998 Circus Train

Fisher Price vintage 1998 Big Top Musical Motorized Circus Train with shooting cannon and trampoline. Works, see video. Plus 5 little people (4 people, one monkey) And a Fisher-Price 2004 Mattel Circus Train with 2 peek-a-boo blocks. This train is supposed move and make sounds.. it did last it was played with years ago, but now I can’t get it to turn on. It does say that it won’t work with low batteries and I don’t have any new ones.. so maybe that’s why it’s not turning on.
