I have my watering can, silver slingshot, silver shovel, axe, net, and umbrella on me at all times. I also have a ton of balloons, a bubble wand, and a tweeter in my letter inventory.
Silver shovel, silver net, silver rod, and golden can, though I never water the plants. My slingshot is attached to the letter you get the very first time playing.
In my pockets I always have my gold fishing rod, my gold shovel, gold watering can, and silver net (Waiting on the bug-off to get the gold.). I have in my hands my throwing beans. I also always have five letters with my gold axe in my first one, my wetsuit in my second, a megaphone in my third, a silver shovel (for ore) in my fourth and a silver watering can in my fifth.
I always have all the tools hidden in my letters.(I have about half of them gold and the rest Silver) plus a diving suit and a hat. So technically my pockets are always empty
I always have my gold watering can and slingshot, then my silver fishing rod, bug net, and shovel. Sometimes I carry around a piece of furniture or clothing for a villager.
