I have a distinct memory of playing with a toy in the 90s/00s that was a torpedo or submarine type underwater vehicle, maybe 18 to 24” long. It was powered by compressed air via a hand pump, which then powered a reciprocating engine and spun a propeller. I remember mine being bright yellow in color. Possibly from Zany Brainy. Does anybody know the name of such a toy, or if they’re still produced?
