|“||It was going to be magnetic, like an inverse boom slime and also come crashing into the world as a meteor. It was very interesting but that second bit wouldn’t make sense on the ranch, and the mosaic slimes were already raining fire, so we pivoted.||”|
— Nick Popovich's response regarding the discontinued Meteor Slime.
It was planned to be added in 0.6.0 However, the devs stated that the slime wasn't working. Parts of it are repurposed for the other new slimes, most likely Fire Slimes, But it's possible that it might come back in a future update, as unfinished code for the slime can be found within the game's files.
