u/Unreasonable_Ending

let me start out by saying i’m a bit of a noob at this game and am kind of learning through trial and error but need some help. with that out the way; are these big enough sized platforms for mobs to spawn on? the platforms are 7x8 and are separated by one tile of water while being in a dirt box with a moat. if they are(or aren’t big enough please lemme know), is that little border of water enough to keep them isolated(?), not that i mind the slimes and everything else fighting but i kind of wanted it like a museum(?)

edit- just a little add on, if this is fine i do plan to put each mob’s respective biome block(s)
