Caveman's Christmas

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.
