Prehistoric Sniffles is a blue anteater who appeared in Blast from the Past. He is similar in appearence to Sniffles, only he has thick eyebrows and wears caveman clothing and has a primitive spear. He is shown to be friends with The Ants. When Sniffles came from the future in his time machine to make sure that everything would be perfect for the playground, he ate an ant as he was leaving. When Prehistoric Sniffles saw this, he also ate an ant (who was once his friend) and decided he liked it. Because Sniffles did this, he started the rivalry between ants and anteaters. He is likely to be Sniffles' ancestor. As he lived thousands of years ago it can be assumed that he died, it is unknown how.
- Other: 1 (One ant)
- It is unknown how Prehistoric Sniffles died, but as he lived thousands of years ago, one can almost be certain he died (unless he was frozen like Cro-Marmot). It is possible that the family of the ant he ate killed him, like the present ants do with Sniffles. (debatable)
- He is the second prehistoric character, after Cro-Marmot.
