Honestly its not even 2 minutes, more like one. and not even that. the first minute of it is in episode 21 at the end so we didn't see anything new. and the other one is cute but it could be still in episode 21 as the first half of this. AND WHERE ARE THE KIDS AND DOGS? Little disappointed about that part, it was cute and all but it could have more depth than this...
Its not really worth (re)watching but if you want a cute short epilogue you can watch in a minute i think you will like it. (but i don't plan on rewatching)
