Jessie gets worried that Zuri may have imaginary friends her whole life, so she tries to find her an actual friend at the park. Zuri meets their neighbor, Mrs. Arthur, but she arrives at the penthouse in character as "Nana Banana", a former clown with a colorful personality. Zuri begins to favor Nana over Jessie. Jealous, Jessie throws Nana out after a banana peel is left on the stairs, which upsets Zuri. Meanwhile, Mr. Kipling falls in love with a plastic toy animal at the park, so Luke, Emma, and Ravi steal it from the park while trying to avoid Ranger Bill (Ronnie Schell), the nearly-blind park security guard. In the end, they get caught, but Nana Banana smooth talks the ruff and burly park security guard.
