Have a drawer or cupboard full of safe things for them to play with - plastic containers, teatowels, plastic kitchen items.

Have a walking toy handy (we have a walking wagon) so bub can cruise around the house with that.

My son spends ages getting his toys in and out of a thing that's kind of like a small laundry hamper . It's from Homemart & it's a wooden structure with cloth sides. It's just his height & he crawls over to it and leans against & to get things out & chucks them everywhere. It cost $5 & is also great storage.

Playing with mega blocks.

Put some music on or one of the toys that has music & dance around the room with bub in your arms or put bub on the ground and dance nearby. My son sits on his bum and goes around in circles on the wood floor to the sound of his Leap Frog maraccas. I just have to put it on & dance in circles & off he goes.
