I decided to write a blog regarding certain alien species throughout 5YL in order to hopefully achieve a more unified understanding with them, starting with the home planet of Armodrillo and Talpaedans, Poiana Lüncas, which while never directly stated in the show itself, has been seen in official CN media, with the 53rd Action Pack declaring it as such, and due to the show never disproving this information, I believe it to be true. The other name I've seen for their planet, Terraexcava has no official sources, and is speculated to be from Bandai's website, but with no proof of such a thing, I find it highly improbable it is true.
