The purse of holding, from Henry Stickmin. That way, I can store everything, plus, I get a nifty purse that's bigger on the inside

a genie in a lamp so I can wish for all my other possessions

My pets

the tardis.

My blanket from birth, i still have it. call me linus lol

Oof.

Can it be anything? Because if so, I want wings.

So long as they're not any bigger then you are, than you can have that. But they'd have to be attached to each other because it's only one thing that you can have.

Ah, okay

Hmm, so according to Google, I would need a wingspan of 6.7 meters to fly.

But if they were that big, they would be too heavy to function...

Oof.

So yeah... No wings for me. :/

Oof size large.

S o u l s sound pretty cool

One trillion dollars

Oh yeah, it'd have to be credit or debit because 1 Tril in cash is way bigger then most humans.

hard choice but prob a crazy made up thing

I would get the reality stone from Avengers End Game and Infinity War and just use it to rewrite reality and change this post to saying that you could have infinite possessions.

I only thought of it after I posted this. Wanted to hear what at least one person had to say before me.
