Which episode of "The Simpsons" is this character in?

Hey everyone!
I remember watching an episode of the Simpsons in which Lisa and Marge both talk to a toy that [I think] Homer gifted to them. The little toy resembled a Jack-in-a-box or a robot I’m not entirely sure anymore, and it kept saying stuff such as “I understand” and nod while the two women were talking to it about their troubles.
Despite this very vague description, any chance anyone knows in which episode I could find this character?
Thanks in advance !
