Snaptrap finds a Fountain Of Youth in the Underground Cities and pours all of it into a new device called, "The Bottle-Ray 2000". It is a powerful machine that can transform anything into a younger version of the item. His plan was to use it on TUFF and all of Petropolis into babies, toddlers, and young children! And it works! But it also turns Snaptrap and his crew into babies along with TUFF. Now it's up to BABY Dudley and BABY Kitty to save the day!
