does it mean that "The rubbery actions of the characters coupled with these sounds and the absence of the narrator of the story gives vivid fun to the boys’ antics"?

Answer

In this context, "abandon" is a noun meaning "without restraint or moderation". 
Therefore, "have the full abandon of the storyteller's art" means "like a storyteller, there is no restraint in the characters' actions." This lack of restraint is what gives vivid fun to the boys' antics.
