It summons creatures to attack you. He hasn't specified what kind of creatures, though...
Doesn't matter. My closest noodles are LAVA NOODLES. Oxygen goes boom-boom. There is no time to travel around the planet before my noodles catch up to him.
Solid oxygen doesnt burn so easily(it is super cold) and even if it catchs up fire it is still solid, so it pushes the lava(lava is not the same as fire, it is melted rocks, it can lose heat eventually) into the volcano before burning out(remember the volcano was partially cooled down by ninja when he was in there).
Then the noodles absorb oxygen(being pushed by a huge block of it should allow them to absorb it) and i send them to do their thing.
The block will burn, eventually, but to get oxygen solid you have to make a lot of pressure, therefore that big block has a lot of oxygen on it(to be big and solid), so it is going to take a while(the while i needed).
Even if you still have lava noodles at your location(space, other side of the world), that might serve as a defence for you, but it wont mean anything to me(and it would take an action to send them).
