The Heeler house transforms into a world of imagination as Bluey and Bingo build an elaborate cubby house for their plush puppy, Kimjim. As the fort grows, it takes over the living room, creating playful chaos that tests Dad’s patience and navigation skills. Meanwhile, Mum dreams of making their space bigger, only to realize that the heart of their home isn’t about size but the family within it. Through laughter, mishaps, and a cubby collapse, the Heelers learn that sometimes less is more.
