What is the name of the DIY store in the episode 'Hammerbarn'?

The DIY store in the Bluey episode “Hammerbarn” is called Hammerbarn.

“Hammerbarn” is the first episode of Bluey’s second series. Bluey, Bingo, Chilli and Bandit visit the store to buy supplies, but the family trip becomes a sprawling game involving trolley houses, garden gnomes and pretend domestic drama.

The name is a playful parody of Bunnings Warehouse, the major Australian hardware chain. This is why “Bunnings” can seem like a tempting answer, but it is not the fictional store’s name in the episode. “Hardware Hut” and IKEA are also distractors rather than names used for the shop.

The episode is especially remembered for introducing the recurring garden gnome named Hecuba, whose role in Bluey and Bingo’s pretend story becomes increasingly dramatic. The title itself combines “hammer,” associated with hardware and home improvement, with “barn,” giving the fictional retailer a distinctly Australian suburban feel.
