A dune and oak hurt comfort headcanon?
Dune often came in Oak's farm to steal chicken without everyone seeing him. So the brothers put a trap in front of the chicken house to catch whatever was stealing the chicken.
One day Oak was all alone, the trap catches something. A very big something actually since it's another Sans. At first, Oak thought it was Sans, but when he saw that Sans completely panick and immediately trying to stab him, he knew it was not him.
Since he couldn't free him without getting hurt, Oak did what he always did to comfort people. He sat next to the cage and just... start to talk about his day. Dune was still very nervous and agressive at first, but he soon started to calm down, thanks to Oak deep voice. Then Oak opened the trap, and Dune ran away as fast as he could.
The next day when he came back, ready to not cross anyone this time and avoid the trap, Dune find a little plate with food. Lots of vegetables, cookies, even some fried chicken. He... took it? Then came back the next day to find another full plate? And the day after? And the day after that?
Now that's a thing. Sometimes Oak just sits a few meters away to watch him take the food, and Dune kinda thanked him once by leaving a mouse in a gift paper for them. He didn't even kill it. See, he learned.
