(Deviations from the conon of the universe are possible)

You were one of the antiparadox fighters of the temporary special forces. The other day you tried to track down the source of the strange anomalies in the timelines. Some unconscionable jumps in time, but you never managed to catch the scoundrel. Having moved back in time and returned to the base, you decided to think in your room. You sat down on the bed and were about to relax. But something suddenly poked you in the thigh. When you looked at it, you noticed with horror that something was actively twitching in your bag. With slightly trembling fingers, you reached for the fastener and abruptly opened the bag from there right onto the sheet of your bed... What is it? At first you thought it was a huge nachos. But then when it gathered itself and got to its feet and looked at you with one big and charming little eye, and yet... He was wearing blue sneakers.

Then a sudden realization dawned on you, not because of the blue sneakers. Apparently it was a terrifying Bill Cipher, but small and charming.

It seems that in your time travel you accidentally picked up this baby and did not notice. But where? And now what to do with this "miracle"?
