TOEM 2 Big Head Mask: Location and Big Head Mode

The TOEM 2 big head mask is a Deltburg pickup with a two-step unlock: find it on screen 10 by climbing the ladder and interacting with the vent, then equip it from the clothing menu. Skipping the second step leaves the achievement locked even though the item is already in the inventory.

Where the Big Head Mask Is

The pickup sits in Deltburg, on screen 10. The documented route is to climb the ladder and interact with the vent on the side of the building to reach the mask.

A second walkthrough describes the same vent from the map side, placing it in Deltburg on the bottom left side of the map. The two descriptions agree on the object - a vent on the side of a building - and differ only in how they describe the position, which is what happens when one guide uses screenshot screens and the other uses the region map.

That is useful when the vent is not obvious on the first pass. Deltburg is the first region the game lets a player explore, and the buildings have side faces that are easy to walk past while looking at the shop fronts.

Why the Achievement Does Not Unlock

The mask and the achievement are not the same event. A clothing-locations guide states the point plainly: finding the mask is not enough for its achievement, and the player needs to equip the Big Head Mask after collecting it.

This is the most common way to lose time on the pickup. The item goes into the clothing collection the moment the vent is opened, so the collection screen shows it as owned, while the achievement is still waiting on the equip flag. A player who checks the list, sees the mask, and moves on will find Big Head Mode missing at the end of the run.

How to Equip It

Equipping happens in the clothing menu. The achievement guide describes the unlock as finding the Big Head Mask and equipping it through that menu, which is the same screen used for the rest of the wardrobe.

The mask is filed as a costume in the location tables, in the group that includes the Hop Mask, the Bing Bong Mask, the Mountain Goat Mask and the Piku Mask. That grouping matters for navigation: looking for it under hats rather than costumes is a way to conclude it is missing when it is not.

Big Head Mode in the Achievement List

The achievement itself is called Big Head Mode, and its listed condition is to find and equip the Big Head Mask. Nothing about the condition mentions a second location or a photo, so the whole requirement is the vent pickup plus the equip step.

The mask also appears in the costume tables with a cost column, which is the game's own ordering of the wardrobe rather than a currency price. Reading the table as if the number were a purchase price is another easy misread, since the vent route is the way to obtain it.
