First, pick which place you'd like to visit and then tap the bubble on the house menu to access that place. Once in your chosen location, you can scroll left or right to visit the entire place. You can add characters by dragging them into the scene from the character tray. If the tray is closed, used the button on the lower left to open it. You can move the characters around, you can drop them onto some of the items in the room (chairs, trampoline, pool, etc.)  and see their reactions. Try different things to discover all of the possibilities in each scene; drag, tap and stack items to play pretend with Bluey and her friends! Note that some places and characters are only available for subscribers.
