I just saw the one-line summary for this ep . . . What happened to Buddy!!? How did he wind up in the hospital?!

Hi,Lucky_Ladybug66! I watched this episode (about Buddy in the hospital) and as far as I remember there was a talk between Charles and the doctor. Charles asked him what had happened to Buddy. And the doctor replied Charles that Buddy had been cleaning the aquarium and then had swallowed the golden fish. After that he wanted to breath fresh air, opened the window and fell out of it.
