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.
GOOD BIT:
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.
