An experiment designed to collect private enemy conversations through his tail is accidentally activated by Lilo, who then gets into trouble after eavesdropping on Nani's phone call with David. Things take a turn for the worst when Lilo overhears part of Mertle's conversation and thinks that she hates her friends. As a result, Mertle, out of anger, willingly helps catch experiments for Hämsterviel in place of Gantu, unaware that he is using her.
- Moral: Don't eavesdrop on others and never jump to conclusions; wait until you have all the facts.
- This is the second time Hämsterviel fired Gantu and later rehired him, the first time being in "Bad Stitch".
- This episode marks Cobra's last appearance in the main Western continuity of the franchise. He would not appear again until the Chinese spin-off Stitch & Ai, premiering years later.
