I've found this to be simple and super cost effective. Prime it black and paint it your chosen color. You can even go back over the glue with some high-gloss paint to make it shiny again. I've got about 9 spore pods that i used this method on. Unfortunately, they got scraped with the new book so they have been sitting on my shelf.
Infact, that might be a new project I work on - Cutting them in 1/2 to make more terrain. I'll need to get MDF for basing however... I must contact El Gigante.
Yep, the paper mache eggs from Hobby Lobby work, too.
