[Super Mario Bros.] When Mario warps ahead from World 1 to World 4, what becomes of the Toads still trapped in the castles of Worlds 2 and 3?

Presumably the Toads remain trapped until Bowser is overthrown, at which point the minions that are using magic to impersonate Bowser in the Worlds 2 and 3 castles flee those castles allowing the Toads to escape.

So the Toads still escape, it just takes longer for them to do so.
