It’s doubtful anyone wants to be swallowed whole by a whale, but that’s what Mark Consuelos found himself doing while guest-starring on the 9-1-1 season 9 premiere.

The Live With Kelly & Mark star guests on the first three episodes of the ABC first-responder drama as tech billionaire Tripp Houser, who is out on a kayak during a board meeting call when he finds himself inside the mouth of a humpback.

“The stunt coordinator was amazing,” Consuelos tells Entertainment Weekly of shooting the scene. “He goes, ‘Are you claustrophobic?’ I go, ‘I am.’ And he says, ‘So am I.’”

Consuelos says the stunt coordinator described the whale mouth set as a “big pistachio shell”: “You’re going to be in it and we can open it whenever you feel uncomfortable.”

The actor and daytime TV host recalls telling them, “As long as you are cool with me saying every now and then, ‘Hey, I need a little fresh air…’ But it was great. It was actually super-easy. They had these palm fronds to mimic the whale’s baleen. They had a bunch of cameras inside, and it was tipping back and forth.”

While it wasn’t the most comfortable day on set, “They were really nice to me,” Consuelos adds. “They used really warm water inside the whale mouth. But as we shot later on in the day, that water was not so warm. But I mean, definitely I checked that off my bucket list of things I didn’t expect to have on my bingo card.”

After surviving the whale, Houser feels indebted to Hen (Aisha Hinds) and ultimately offers her and a plus-one a ride in his spacecraft. (Doesn’t hurt that it also helps his tainted public image to send some “real-life heroes” into orbit rather than some Real Housewives.)

The season 9 premiere ends with Hen and Athena (Angela Bassett) preparing for liftoff. But this is 9-1-1, so “everything that could go wrong has gone wrong,” Consuelos says of what happens in tonight’s second episode.

“It’s like being on a boat,” he continues. “All of a sudden we have a fire, and it’s gone black and we have no idea what’s happening. We only have a very small window to communicate with the vessel, because the satellites are down. The worst thing on a boat to happen on a boat, even if you’re in the middle of water, is for the vessel to catch on fire. And I think the only thing worse than that is for that to happen in space.”
