The rest are for me by zarla The rest are for me by zarla
Someone asked if Gaster ever did the marshmallow test on the brothers and I'd never heard of it before! The image of one of them petting a marshmallow was just too adorable to resist, haha. Also something for those who wanted to see Gaster have trouble picking something up with his hole hands. The brothers would be around like 4-6 here probably, mentally.

Goatdad dads you. Alternate ending: Gaster leaves them both in there, gets a phone call, then completely forgets about the entire thing for like an hour before remembering and coming to get them.

Some alternate panels:

Gaster could just pick the sweets up with his fingers though.
Or maybe he could put some gloves or something over his palms.

I saw a program where some people did this test with crows, though with bread and cheese instead of candy.
The crow was given a piece of bread in its beak, then presented to it was a piece of cheese.
The crow liked bread but loved cheese, so instead of eating the bread it kept it in its beak for a period of time until the person gave the cheese, trading it for the bread.
The crow did not care for grapes however, so when they gave it another piece of bread and presented a grape to it, it ate the bread right away.

At the same time they showed a video of some young kids (5-8 years I think) taking the test too, but with chocolate bits.
One of the kids ended up putting the chocolate in the mouth, then taking it out again, just tasting the treat XD It was so cute! <3
The majority ended up getting two chocolates, I don't remember if any of them gave in to the temptation though.
It was a program about bird intelligence, starring crows, parrots and...I'm not sure if there was a third bird involved, nor what kind it was, but it was an interesting program.

What if he used those magic hands of his to pick up the candy instead?
No, wait...they also have holes. Dammit!

At least you're still getting the sweets instead of them just falling through the holes in your hands.

I wonder if Gaster had a camera and was watching them the whole time. If so, I wonder how he reacted to all their little actions to keep from eating it XD

Do skeletons actually say "nom" when they eat? I can't see how else those marshmallows could stay inside them. Then again, magic food.
