Elon Musk is here to save the day, even though it's probably not necessary.

The CEO of Tesla and SpaceX was — if his Twitter and Instagram accounts are to be believed — in Thailand on Monday touring the cave where a team of 12 soccer players, aged 11 to 16, became stuck with their coach on June 23. Musk says he's there to help, and you better believe he brought his kid-sized submarine with him.

Importantly, as of the time of this writing, eight of the 13 trapped people have already been saved by the heroic actions of rescue divers and support teams. Musk, who has been documenting his efforts to build the aforementioned sub to possibly help in the rescue, still clearly felt like he had something to offer.

"Just returned from Cave 3," tweeted the CEO. "Mini-sub is ready if needed."

Just returned from Cave 3. Mini-sub is ready if needed. It is made of rocket parts & named Wild Boar after kids’ soccer team. Leaving here in case it may be useful in the future. Thailand is so beautiful. pic.twitter.com/EHNh8ydaTT — Elon Musk (@elonmusk) July 9, 2018

"Thailand is so beautiful," he added.

Musk also acknowledged the hard work of the rescuers on the ground. Which, yes.

Thanks, but we’ve not done anything useful yet. It is all other people. — Elon Musk (@elonmusk) July 8, 2018

Five people remain trapped in the cave, and according to the New York Times, the plan is to rescue them on Tuesday.

No word on whether Musk and his kid sub will play a role.
