WABAC Machine

The Wormhole Activating and Bridging Automatic Computer (or WABAC, pronounced wayback) is a time machine Mr. Peabody invented for Sherman in both the original 1960s cartoon and 2014 film. Its title is a play on names of early computers such as the UNIVAC and ENIAC, reflecting Peabody's love for puns. It is an extremely major plot point in the franchise as it serves as both Mr. Peabody and Sherman's means of having adventures as well as the symbol for Peabody's love towards his boy/son.
