The story unfolds among three very different worlds... the "real" world of comic-cons and safari parks, Groo's world (both cartoon-illustrated by Sergio Aragonés), and Tarzan's world (realistically illustrated by Thomas Yeates).
Tarzan's chimpanzee is unnamed in this story.
So that Groo might raise an army of fighters for Tarzan, ever-loyal dog Rufferto leads Groo back from Pal-ul-don through the cavern passages to Ungara - by a unique method...
RUFFERTO 1(thinks): "I am just following the smell of Groo IN REVERSE!
RUFFERTO 2(thinks): "You leave a little of yourself wherever you go!"
Topics include: Mark's insistence that a reader's letter has arrived too late to get into this letter column - in response to that very same letter... TWICE, Groo crossing over with Usagi Yojimbo, and praise for Rufferto from a reader's dog.
