S2E60 Brainchild

Oggy stumbles over a chubby kid who’s sitting on the sidewalk, engrossed in typing on his laptop. To Oggy's dismay, the boy decides to tag along home with him. Frantically, Oggy attempts to reach out to Jack for guidance, but his efforts prove futile. Meanwhile, the surprisingly clever kid begins conducting bizarre experiments on Oggy's cockroaches. Realizing he’s in over his head, Oggy ultimately decides to contact the FBAÏ (Federal Bureau of Analgesics Ïo) for assistance.
