i'm in the same boat as >>536264428 in that it doesn't really need an explanation and doing so would ruin it, i think the theorycrafting about ado and shiver star with robobot making people think haltmann had something to do with it is more fun than if the games actually tried to explain stuff.
adeleine being there does have an explanation though, 64 manual says she came to pop star to study art, so she's probably some planet hopper of some sort. as for how she got there, i just think warp stars are just a common thing in the universe and are basically a galaxy wide taxi service, all the ones that are in the games are just parked aside from kirby calling in one in 64.
