What is the Jerry daycare introduced in Mortynight Run called?

The Jerry daycare introduced in “Mortynight Run” is called Jerryboree.

Jerryboree is a daycare facility designed to look after different versions of Jerry from across the multiverse. Rick leaves Jerry there while he and Morty pursue an adventure, treating the center as a practical service for travelers who cannot—or do not want to—bring their Jerry along.

The joke depends on the show’s multiverse structure. Because countless realities contain their own Jerrys, the daycare’s staff must identify and manage multiple nearly identical guests. That produces one of the episode’s signature absurdities: even Rick and Jerry can lose track of which Jerry belongs to which family.

The name is a pun combining “Jerry” with “boree,” evoking a gathering or convention. Viewers sometimes misremember it as “Jerrydome” or “Jerryland,” but those names are not used in the episode. “Mortynight Run” is also notable for introducing Krombopulos Michael and the alien arcade Blips and Chitz.
