As the sun sets and before Kame-Sennin, Gokū and Kulilin prepare to eat, Kame Sennin informs the two young men of their training regimen resuming the next day at dawn, but not before Kame-Sennin tests them again. This time around, Kame Sennin marks a stone, throws it into the jungle, and instructs the two young men to find the stone within 30 minutes, or otherwise receive no dinner. As the two young boys scurry to find the stone, Kulilin decides to pick up another rock, mark it, and give it to Kame-Sennin as a means to deceive the master and cheat his way into completing the task.
However, this does not fool Kame-Sennin, and Kulilin is forced to find the actual stone that Kame-Sennin threw. Gokū eventually finds the stone thrown by Kame Sennin, but Kulilin tricks Gokū into giving up the stone. After a brief struggle between the two, Kulilin is able to return the stone to Kame-Sennin, causing Gokū not to receive any dinner at the Kame House. Ironically, Gokū ends up being fortunate to miss dinner, as the fish Lunch cooked causes her, Kame-Sennin and Kulilin to be sick and bedridden for three days.
