Okay, so I'm posting a lot of unused textures (some of them might be used, sorry.)
Named ailtranslucid, don't know what it would've been.
Named air_pump. Probably an air pump (Thanks captain obvious

)
Early version Hoodmonger Soldier as you can see in concept arts!
Named gour_body. Scrapped character?
Named plum_plant. Maybe Globox could do, like in Rayman 2, grow a plant with his weather power
Named wmelon_fruit. Watermelon in Rayman3?
Named flam_0X (X because there's multiple frame animations, here it was 6), appears in Desert of Knarrens texture.
Same as upside.
Again in DoTK, named kna_charcoal. DoTK was supposed to have lava too?
named dead_veget. Again in DoTK
Probably an early magic door for Land of Livid Dead
An early grass of LoTLD, that can be seen in early screenshot.
Dunno what it could meant, in lotld.
A flag of all cans. In SMBC
A bird.
A tree in SMBC textures, kinda odd since it's supposed to be winter, the tree seems to be like in Autumn.
Other snowman.
Todo:
Get the rest in DoTK, Leptys, SMBC, and other stages.
