There's a video of Starlight Cradle.

No, I'm not saying add it and the Slooms back in (though I would like that, if the status is ever fixed).

I'm saying add in areas randomly in Lichenous Lairs and Clockwork Tunnels that are similar to the areas seen there, except with a different background and the Slooms would be replaced with the correct theme Lichens, and the Sloombargos would be replaced with Giant Lichen Colonies (or, in poison levels, Toxilargos).
