Iroh explains to Kai and Mako how he started to grow uncontrollably. Seeing as how the spirit is acting like a parasite, causing this size development; Mako decides to travel inside Iroh to stop this spirit from making Iroh grow even further. Mako acts Kai to tag along, but choose to loaf on Iroh's crotch instead. Before Mako goes inside Iroh, he takes out a shrinking potion for himself, so he is able to cover more ground within Iroh (They've tried using the shrinking potion on Iroh, but it didn't work). Mako also mentions how Varrick was the creator of this potion, and how he played around a bit with Mako as well. Will Mako be able to find the spirit? Will Kai arrive on time to pick up Mako? Stay tuned!
