Ever notice how in Rick in Morty, they really strain to keep continuity through small details?
>All through season 2, there is a giant crack around the house where it was moved through dimensions
>Later episodes include damage done to it with patched holes
>The green rocks Rick throws away in Total Rickall are the same rocks Rick put in his trunk after Morty killed Fart, and those rocks had small parasite color patterned eggs attached to them...

So I'm left wondering. What happens to the rat in this shot? It seems to be getting of the time testicles' time bubble in a frame that looks kinda like the prison Rick's in. Maybe part of the S3 opening?
