Nintendo just released their Dream Island for the public to see from March 10 to March 24 and they designed it based off of the brand new Mario Items.
You can see the full island tour here, but if you to experience yourself, or just see screen shots, here is the code below:
Dream Code: DA-6382–1459–4417
LEVEL 1 Overworld:
Simple layout with some water areas to remind you of the first level of Mario
LEVEL 2 Underground Cave:
Reminds you a bit of the caves Mario runs through and there’s a small treasure at the back!
LEVEL 3 Mario’s Room
All of Mario Theme Items in one convenient Room… And there's a secret workout room
LEVEL 4 Mario’s Mementos
This one is cool.
UPDATE: Ok so here are my guesses for the item Mementos
Mushroom — Super Mario Bros
Mushroom Log — Super Mario Bros 2
Tanuki — Super Mario Bros 3
Rainbow Feather — Super Mario World [Star World = Rainbow theme]
Turnip — Super Mario Land [I know it could be Super Mario Bros 2.]
Feather Hat — Super Mario 64[WingCap]
Water Pump — Super Mario Sunshine
Star — Super Mario Galaxy
Bubble Wand — New Super Mario Bros Wii. [Respawn Bubble]
Cat Ears - Super Mario 3D World
Top Hat — Super Mario Odyssey
The top part… I’m not sure what they are. I think powerups? Someone tell me what they think they represent!
LEVEL 5 Bowser’s Castle
You have to go through a mini course and you’ll end up at the castle!
Pretty short and sweet, it’s a nice token of appreciation to Mario’s heritage to the Animal Crossing World
