From Bubblegum Wiki

It's a Date Thing

Josh-chan decides he's too lonely for self-dependency and tells Katzie it's time they "dated". However, doing the exact things Katzie wanted to do, they soon have Shin on their case, trying to prove a point for all neighborhoods. Then, when the gang accidentally wind up on a "romantic dinner" with Marge and Tammy, the differences escalate into a "battle of the sisters" to see who can survive the dating ordeal. Josh-chan seems to be heartbroken at first, but when Shin starts to help Josh and Katzie gets back together things begin to go uphill.
