Time Blasters

Tells the adventures of David and Ben who use a time machine to go back a few days, in order to retake a test that they failed.

David's brother, Darrin, just invented a radio-controlled pooch. It performs tricks, mixes delicious smoothies, and grows 50 feet tall. When David's friend brings back a T. Rex from the past, Robo-Dog 3000 turns into the ultimate fighting machine. It's beast versus bot in the smackdown of the century!
