That's your metaphysical assumption. It doesn't follow from QM.
If one starts from a logically consistent system, then one can always find a physical
system whose equations of motion realize it, it will then exist in a generic multiverse
scenario.
In that case, how do you define 'physical'?

Anything 'could be'.
That's my point. Anything 'could be' if the only constraint is logical consistency
(not self contradictory). But in the sense of 'be' that requires a universe and
observers there appear to be other, nomological constraints. So there could be an
animal that looks superficially like and elephant and lives on a planet who's
atmosphere is as dense as water and is pink. But it couldn't also have the same DNA
and metabolic system as and elephant. So it would only 'be a flying pink elephant'
because we use the words to denote a certain similarity in appearance.

Question: would such "anything" be topic for this physicalist-based conventional
EVERYTHING List?
Q-2: are OUR colors defined for different physical circumstances as well? BTW - IMO
flying is not restricted to a conventionally called 'gaseous' medium, so 'swimming'
can be considered an alternate for flying. - PINK Whales? <G>
Rem: of course 'they' all exist - if not otherwise: in our mind.

this list.
In the MWI or in eternal inflation models, everything that is not
strictly
forbidden by the conservation laws will happen.
Flying pink elephants can e.g. exist on planets with an extemely dense
atmosphere, there was a NGC documentary a few years ago about this
topic, it was
suggested that you could have flying whales on such planets.
Could you identify them as elephants and whales by their DNA? Could the
elephants
be pink?
