Similarly to having a Moshling Zoo collection of Moshlings, Moshling Rescue! features tree house sets of the Moshlings you have rescued. Moshling Rescue's Pinterest lists 107 Moshlings, including Big Bad Bill. While the biographies of the Moshlings in Moshling Rescue are the same as those in Moshi Monsters, Moshling Rescue's Pinterest listed biographies of Moshlings in which they introduce themselves and explain where they are to be found and plea for help. These also include Moshlings that are not yet in-game and thus suggest to be upcoming.
