Two Point Museum has a wide assortment of quirky characters who will come to see the Exhibits that you have on display. From flamboyantly-dressed enthusiasts to actual aliens from outer space, nothing is too strange. There’s one guest type in particular, though, that requires a lot of extra work if you want them to come and visit; the Cave People.

Cave People are hard to come by in 2025, so if you want them to buy a ticket and see what your museum has to offer, you’ll have to get creative, and bring them from the distant past.
How To Get The Time Portal
To get Cave People as guests, the first thing you’ll need is a Time Portal. There are two locations where you can find these; Spoony Dunes in the Bone Belt, and Alternate Yesterday in the Netherworld. Of the two, Spoony Dunes is much easier to reach and is less dangerous.
It also gives you a chance of getting Lone Henge, which synergizes well with some of the later Expeditions you’ll be going on in your quest for Cave People.
Spoony Dunes Expeditions
In the Spoony Dunes, you need to bring two Prehistory Experts. Try to have their combined level total ten or higher to negate most of the dangerous Events and give you a chance at a better-quality find. You should also pay attention to which season you depart, as sandstorms and heatwaves at additional dangers.
A First Aid Kit can neutralize the heatwave, but if the helicopter gets caught in a sandstorm you’ll have to pay to repair it before it will fly again.
Alternate Yesterday Expeditions
Alternate Yesterday requires one Supernatural Expert and One Security Guard. Unless your Expert is at least Rank 20, you won’t be able to counter all the events, so bring someone who at least has two levels in either Survival Skills or Analysis to counter either Ectoplasm or the Spectral Rift.
The Security Guard should have one level in Camera Room training for a chance at an XP bonus. Whatever you do, don’t go during Nightmare Season, as there’s a chance your explorers will be permanently devoured by the horrors of the Netherworld.

Time travel is a theme often used in video games for story purposes or combat mechanics. These games are worth the time (sorry) to play them.
How To Activate The Time Portal
Once you have a Time Portal placed in your museum, you’ll need several Space Exhibits that can only be retrieved by venturing into the Known Universe. In the story campaign, you’ll need to progress the Pebberley Heights museum far enough that you can reach the Space Gibbon homeworlds in order to get everything required.
Specifically, activating the Time Portal requires the following:
- Two Celestial Cells (Circle) from Two Point Orbit.
- One Celestial Cell (Square) from The Moon.
- One Blending Gears from Gibbon Moon One.
You can send the same Space Expert to each location in turn until you have everything you need; if they’re a new hire, go in the order shown above to help them level up. Make sure that they have the Pilot Wings skill to avoid damage to the helicopter, and if they aren’t a high enough level to counteract Meteormites (4 in Two Point Orbit, 6 on The Moon), send them with an Illness Elixir to keep the contagious disease from coming back to Earth with them.
If you get a Triangle Cell, you can use it to activate Lone Henge, signaling to alien species that your museum is open for business; they’ll start turning up at the Ticket Booth as long as the Henge remains active. This is how to get alien visitors on maps other than Pebberley Heights.
Once you have all the parts, place them together with the Time Portal so that they’re all within range of one another. The Cells will activate the Blending Gears, which will work with one of the Circle Cells to activate the Time Portal. If you’ve done it right, the Portal will start glowing purple. As long as it stays active, the Time Portal will spawn a Cave Person visitor periodically.
Cave People still have to buy a ticket before they can start going to Exhibits, so try putting a Ticket Booth near the Time Portal.
Making Cave People With The DNA Designer
You can also use the DNA Designer to transform existing guests into Cave People. They’re functionally identical to those that come through the Time Portal, but the game won’t count them toward your Sticker Book total, since it tracks them when they buy their ticket.
Cave People As Guests
Cave People leave reviews based on their overall Happiness, so make sure that they have ready access to Cafeterias, Bathrooms, Benches, and other comforts. Knowledge doesn’t do much for them (they haven’t yet learned to read modern languages, though the pictures on Info Stands mean Knowledge isn’t completely useless), so Buzz is the next-most important trait for them. They get additional Buzz from Prehistory Exhibits, which remind them of home.
Non-Cave People get Buzz for seeing living Cave People walking around the museum, making them beneficial to have as guests.
It’s unclear where Cave People get modern money, but Cave People prefer to buy posters and plushies in the Gift Shop. Oddly, when their visit ends, they leave by the normal museum exit instead of returning to their own time through the Portal. A Cave Person that sees five or more complete Dinosaur Skeletons by the time they leave will have their Dream Visit requirement fulfilled, leaving a great review and donating heavily.
