On an island somewhere, the parents of the missing kids ask the G5 Marines for help, but the Marines tell them that their kids died in an accident and to stop bothering them. Meanwhile back in the icy cave in Punk Hazard, Usopp and Nami have trouble controlling the drug addicted kids, and to make things even worse, Ceasar appears with a bag of drugged candy to reclaim the kids. Near the lake, Sanji's group can see the slime monster is spitting itself towards the lab, and so the group decide to run to the lab as well. In the lab, Luffy's group along with Law, Tashigi and Smoker are locked in a cage with Vergo and Monet keeping watch. Vergo is the Vice Admiral in command of the G5 Marines but is also involved in Ceasar's operation. Vergo tells Smoker and the other captives that they are all going to be killed to keep the lab a secret. In the cage, Luffy asks Law about the "Joker" character, and Law explains that the Joker is a shadow broker whose real identity is Doflammingo, and Law knows this (as well as Vergo) because he used to be Doflammingo's subordinate.
