My idea for this is that the SCP consists of two pieces of paper.
One has the picture of a pixel dog (like Undertale's Annoying Dog design) printed on it, towards the top.
The other is blank save for two words at the top, reading "My Dearest".
The general gist of the SCP is that when the two sheets of paper are touching, the dog will become animate and "travel" over to the other sheet. The longer the dog stays on the other sheet, more details are added to the paper.
Firstly, words are added. They form a poem, mostly speaking about the writer and the writer's lover, at some point in time. The writer looks out in the distance and sees a small dog.
After the poem appears, other details are added. Scenery that correlates to the poem slowly appear. The dog can interact with the scenery.
When the two papers are separated, all the ink disappears from the page and the paper reverts back to its original state, which is the dog on one sheet and the words "My Dearest" on the other.
Any critque? If possible, could someone rake through the database and tell me if there are any SCPs like the one I described?
