Sonic Underground
S01E08 Who Do You Think You Are
Rumors suggest that Queen Aleena's royal journals lie hidden beneath a palace in Tashistan. As Sonic and his siblings search the city for the scrolls, disaster strikes when Sonia gets accidentally knocked on the head during a scuffle, leading her to lose her memory. Things worsen when she unknowingly sells her power medallion to a local trader. A young boy from the village tries to protect Sonia, but they are soon captured by Sleet and Dingo. Now, Sonic and Manic must join forces to recover the medallion, find the journals, and rescue the one thing that matters most to them: Sonia.
