The name "Golumbina" is a joke between a friend and me from a voice recording I made. Golumbina in a tiny, very hyper, no brain version of my sona Seasta.
Shes obsesed with julmust/påskmusk which is a christmas/easter soda in sweden.
Can be seen as a crazy little mouse
No clothes
No pupils except for when in smug "time to cause disaster" expression.
Does not have a concistent size.
Can ride Drum like a horse.
