Petrahydrox's ability triggers only if it's on the battlefield when it becomes the target of a spell or ability. (2024-01-12)
Petrahydrox's ability resolves before the spell or ability that caused it to trigger. It resolves even if that spell or ability is countered. (2024-01-12)

If the spell or ability that targets Petrahydrox has no other targets, it won't resolve (because it no longer has a legal target after Petrahydrox has returned to its owner's hand). (2024-01-12)
