In "Morty's Mind Blowers", it is suggested that Rick and Morty might have left this dimension when Morty intercepted a highly sensitive conversation between three Squirrels (which eventually lead to a squirrel apocalypse), although this has yet to be confirmed.
Being too lazy to change things back to normal, Rick traveled to an alternate dimension where his counterpart had been lucky with the situation (and did fix it) and was also conveniently killed by a failed experiment alongside Morty. When they arrived, they took the dead bodies of that dimension's versions of themselves, buried them in the backyard, and continued in this timeline. It is possible, though unconfirmed, that after Morty had a problem with a group of squirrels, he and Rick had to leave for yet another dimension. If this did happen, it presumably did sometime before "Morty's Mind Blowers".
The name of this current dimension is currently unknown.
It is possible but unconfirmed that, before the events of "Morty's Mind Blowers", Morty and Rick started living in a different dimension.
