Adventures of Sonic the Hedgehog

Momma Robotnik Returns (1x21)

:

Mama Robotnik once again escapes from the asylum (see "Mama Robotnik's Birthday"), and returns to wreak revenge on Sonic, notifying the law that a homeless minor is roaming the streets, and offering to adopt him. The minor you ask - Sonic! The courts forcibly place him under her care even without Sonic's pleas, and she imprisons him in her fortress, using Tails, locked in her torture chamber, to keep him there!
