Yayaball's Tiny World: Part Two
Maetel and Tetsuro remained in Yaryabol's mansion to find out what actually happened to his mother. But instead Tetsuro was lured to a trap designed to kill him but managed to (barely) escape. Maetel confronted Yaryabol but was herself restrained by Yaryabol's mother, who ordered him kill Maetel. Though initially reluctant, Yaryabol succumbed to his mother, only to be stopped by Tetsuro. Tetsuro discovered that Yaryabol's mother was a crude robot, and her consciousness was transferred to a supercomputer by Yaryabol. Tetsuro destroyed the computer in a final confrontation, and Yaryabol was devastated believing he was unable to achieve anything without his mother on his side. Meanwhile, the Conductor managed to convince C62 to reverse its course to retrieve Maetel and Tetsuro.
