Also from Nobiax Mundi pack is the cactus mesh. The original is a 3 arm job, see image below:
I converted the mesh to md3 and reduced the graphics to 512 x 512. After that I progressively disarmed the model, so there are now 4 meshes, one with no arms, one with 1 arm and one with the classic 2 arm hold up pose. The 4 meshes, configs and graphics are less than 500KB and are in the att. cacti.rar
