Ace Hart adventures in Jurassic Bark complete with the Bugsy Vile gang, while Eliot helps Artie grapple with the trials and tribulations of creativity. We also meet new characters for this season such as Yves'n Steven-Yves, a cat burglar whose attempts at stealing the guarded prized possession are always foiled by Steven, the happy go lucky guard dog. We get an introduction to Dot, Rosie's niece in the adventures of "Rosie and Dot." Finally we meet Mr. Moogie, Artie's animated squeaky toy.
