From a roleplay me and a friend have been doing for almost 2 years now.

After going through a portal to a strange new world, Donut and his allies examined the place, but after the portal closed on its own, they wondered how they would get out. They sought to open a portal themselves, Donut opening a portal 1st, or at least trying to.
The Portal opens and it seems to be pitch black. Wondering if it would actually work, Donut himself volunteered to test it. He put his hand and paw into the portal and the portal nearly pulls him completely in it, but he managed to quickly break free from it. After Dean, one of the team members, checked it, him and Zero noticed that the liquid the portal was made of was nothing but pure magic. The liquid began hindering the movement of digits quickly, Donut's fingers and toes on his paws nearly immoveable as the thick magic tried to hold them in place.
Donut decided to close the portal and assign portal duty to Ozone, who could successfully create world portals in this new world.
Seeing the problem it caused, he eventually afterwards fused the half of his body that was covered in it to it. Dean quickly warned Donut of the dangers it could cause, eventually stating that the magic would eventually take over Donut's body if he isn't careful, eventually prompting Donut to get rid of the fusion and pure magic all together, for now.



Btw, I referenced a base for the picture and if anyone happens to know the owner of the original base (If you recognize it), let me know. Considering I'm now posting this picture here now too, I would really like to give credit to the OG base creator.
Unfortunately, I can't track down the owner of the original base I referenced, as my phone ended up wiping alot of my old pictures from the device a while back, so I can't track them down myself.
Credit goes to them for the base I referenced. Hopefully I can track them down at some point so I can list their name on this.
