Flabber, the house monsters and the kids try to save Mums when he gets "mum-napped" by the same archaeologist who originally found the tomb. Also an artifact that was stolen by the fortune-seekers contains a curse that it is making their lives miserable! The only way they know how to nullify the curse is to return Mums to his tomb. Will the BeetleBorgs be able to reunite Mums with the tomb and the artifact?
