Glamburger
And every time we try to change something for the better, he vetoes it and says "that's not how they do it on the surface."
Oh! Right!
Humans are always eating hamburgers made of SEQUINS AND GLUE.
The Glamburger (JP: グラマーバーガー) is a consumable item sold at the MTT-Brand Burger Emporium. Eating a Glamburger makes a special sound effect, except in Serious Mode. The protagonist can also find one in the trash can in the CORE near the warrior's path before reaching Mettaton. Despite the game's hints to the contrary, it is not possible to actually give or sell one to Bratty and Catty.
- Eating a Glamburger during Mettaton EX's fight provides 500 rating points. The viewers "admire" the brand.
The Glamburger's original description was "A hamburger made of glittery sequins. Eating it makes you more popular, but it's expensive." according to the update #26 on the Undertale Kickstarter.
- The word "Glamburger" is a portmanteau of the words "glamorous" and "hamburger".
