“THE KOALA WHO WALKS LIKE A MAN!” An experiment with a cute koala bear turns into an acute problem for Ambush Bug!
A man walks into Ambush Bug's Detective agency. He has a problem. There is someone after him, and he wants to hire the bug to stop him. See the man trying to hire the Ambush bug is a scientist. A scientist who is trying to remove and harness the cuteness of a Koala bear. A homely Janitor notices that one of the scientist decides to inject himself with the Koala cuteness, causing the janitor to change into a Koala bear of Kong like proportions. Causing no one to run in terror, but to say "Ahhhh" when he terrorizes the city. We are also treated to the first appearance of Jonni DC, the continuity cop.
And of course at the end, we are told next issue he faces Darkseid.
