Use a spawn egg in creative or look for a nether fotress where they spawn.
Are u asking how to spawn witches? (well you go into creative and you look for a spawn egg and you will find a witch spawn egg) or are u asking how do they spawn? (Well they spawn at night) I hoped that helped! ~Magpie
Basically get a dark room and monster will spawn there. And then build a trap(look on Youtube). Hopefully Creepers will spawn in there and it will kill them. Other items will be collected like Arrows, Bones, String and Feathers.
Go into the place where you can spawn stuff and spawn a platform and just rotate it like a wall.

This depends on the games which you are playing. However, usually you will have to step on a button which will then spawn a boat.
Ectoplasm looks like spawns cape from the movie spawn to best describe it, its dark like crude oil and it flies through the air passing through solid objects.

Witches can spawn in one of three ways:Naturally at night (recent update, lower chance of spawning)In Witch Huts (found in Swamp biomes)Through the use of a Witch spawn egg (creative mode only)
In roblox studio you insert a spawn of course. Next, you add a tool you want people to spawn with and press yes to "would you like to place this item in the starterpack or in 3D view?"
