Terraria 1.4.5 (“Bigger and Boulder”) includes a small Palworld crossover with collectible Pals that function as combat helpers or utility tools.
Quick answer: Cattiva and Foxparks appear on the surface alongside goblin scouts; Chillet comes from a “Huge Dragon Egg” underground; Digtoise appears in the underground desert and is detected via a metal detector.
Palworld Pals in Terraria 1.4.5
| Pal | Where it appears | How you collect it | What it does |
|---|---|---|---|
| Cattiva | Surface, near goblin scouts (often in the outer thirds of the map; avoid Hallow, Corruption, and Crimson) | Defeat the goblin scouts in the encounter; Cattiva becomes an item you can pick up | Summon for combat; benefits from whips that tag targets for minions |
| Foxparks | Surface, with the same basic condition as Cattiva (goblin-scout encounter) | Defeat the goblins in the encounter; Foxparks becomes an item you can pick up | Appears as a “sentry” style Pal in the crossover, and can be carried like a flamethrower |
| Chillet (and Chillet Ignis) | Underground as eggs; metal detector reads “Huge Dragon Egg detected!” | Mine the egg, then right-click the egg item to hatch a Chillet | Mount summon; double-tap a direction to do a Rocket Slam that damages enemies |
| Digtoise | Underground desert biome (not necessarily the cavern layer) | Find it via a metal detector alert, then mine the spiked shell you see | Mining-focused summon; left-click to guide it, right-click to recall it |

How Cattiva spawns and how to know you got it
Cattiva’s key condition is its association with goblin scouts on the surface. It doesn’t drop like a normal item at first glance; the encounter resolves into a pickup after the goblin scouts are dealt with.
How you know it worked: after you clear the nearby goblin scouts, Cattiva turns into an item on the ground that you can pick up.

How Foxparks spawns and how to know you got it
Foxparks shares the same general encounter pattern as Cattiva: it’s tied to the goblin-scout surface spawn. It can show up in the same places you’d hunt Cattiva, though Cattiva is described as the more common spawn.
How you know it worked: after you defeat the goblins in the encounter, Foxparks becomes an item that can be picked up.

How Chillet eggs work (including Chillet Ignis)
Chillet (and its variant, Chillet Ignis) is found as an egg underground. The practical “tell” is the metal detector message: Huge Dragon Egg detected!
Once mined, the egg is handled like a hatchable item: right-click it in your inventory to hatch, producing a Chillet (with a random color noted for the hatch result).
How you know it worked: the egg item is consumed on right-click, and you receive the mount summon.

How Digtoise spawns in the underground desert
Digtoise appears in the underground desert biome and is detectable using a metal detector. Visually, it presents as a spiked shell you can mine with a pickaxe.
After you collect it, Digtoise acts like a guided mining companion: left-click sends it where you want it to work, and right-click recalls it.
How you know it worked: the mined shell becomes a collectible item, and after use, you can direct/recall the summon with the stated inputs.

Pal Metal Armor vanity set
The Palworld crossover also includes a Pal armor set. A Pal Metal Armor vanity set (chestpiece and leggings) can appear in the Traveling Merchant’s inventory, with a total cost of 10 gold.
