Slimy x Stingy x Inside a Cave
Gon, Leorio and Kurapika become trapped in the cave with Ponzu. Leorio has been poisoned, and Gon gets bit numerous times to retrieve the antidote. Gon uses Ponzu's sleeping gas to put the snakes to sleep while holding his breath and rescuing everyone. Leorio takes Ponzu's number badge while she sleeps and Gon retrieves the number badges given to him by Hisoka, reasoning that it's OK to use them so that he can remain with his friends. The fourth stage ends.
