Caveman's Christmas S01E13
This is the only episode that Flint and the team travelled back in time not just one, but two. It started on Christmas Day where they will also meet a lonely young girl named Maria in ancient France in hopes of finding her missing mother and that is with the help of her own-believed angel which is the Time Shifter named Elfin (which he has an ability to turn anything into a toy). As Flint works to prevent the death of Maria's mother, they also must deal with Petra Fina even when she transforms Elfin to Elfin-Con. They defeat him with the help of Batterball-Master. Afterwards, Jillian Grey stated that tampering with history is illegal. Though she will overlook it.
