Sergio Aragonés The Groo Jamboree (2000)

Groo has but one friend in the world - the loyal, royal pooch known as Rufferto. So what happens when Groo (stupidly, even for him) thinks he's eaten his one friend in the world? This two-part tale from Groo's past, plus two more equally silly tales by Eisner winners Sergio Aragones and Mark Evanier, comprise the Groo Jamboree!
