Kenny the Koala has always been there for Luke during countless days and nights, until one day when his obsession crosses the line. Luke must make the biggest decision of his life. He can either give up Kenny or embrace him until the end of his days. Meanwhile, Stuart is devastated that Zuri continuously tries avoiding him and he devises a plan to make her jealous by flirting with Emma instead, despite Emma's annoyance. Convinced enough, Zuri does become jealous and pleads with him to get over Emma. Back on the terrace, Kenny accidentally slips out of Jessie's hands as he gets torn up by a car and a horse, causing Luke to go into a deep shock while accusing Jessie for this mess. Near the end, Luke, saddened by Kenny's sudden fall, reveals why Kenny is so important to him and that he was his only family until Morgan and Christina brought him to the city of New York. Zuri apologizes for taunting Luke all this time and they have a brief embrace. Stuart successfully fixes Kenny, as Luke thanks him and Ravi for saving his best friend from a near-death experience.
- This episode was originally scheduled to premiere on May 17, 2013 but was temporarily shelved because the original version had references to gluten restrictions in the character's diet, which was deemed offensive to people with gluten intolerance; instead a re-run of the episode "Kids Don't Wanna Be Shunned" was shown to fill in its place. The edited version of "Quitting Cold Koala" finally aired on July 5, 2013, with all the gluten jokes having been removed in the revised version.
