The Fiesta Host is an Aztec Ghost

The gang is on their way to Mexico for the fiesta but the party is canceled. The owner of the hotel that they are staying in tells them about the ghost of Katazoma, a dead ruler that has come back to seek revenge on those who disturbed his rest. Things get even more weird when a strange stone statue comes to life.
