These are VHS tapes of the Adventures of Sonic the Hedgehog show. Each tape has about 1 hour of entertainment. (So, about 3 episodes only)

They are also titled. The first is "One Hour: The Video with Attitude", the second is "The Hottest Hedgehog in the Galaxy" the third is "High Speed Heroics" the fourth is "Close Encounters of the Sonic Kind". The 5th tape was released at the same time, but it is different. It's longer than the others because it has the "Chaos Emerald Caper" episode set that was always shown at the end of this series' run, all collected together. That one is called "The Quest for the Chaos Emerald" & you can see the back has little mini ads for the other tapes if you didn't already have them.
