Dendritic Cell O678’s behavior shifts subtly but unmistakably when he drinks his bottle of Lactic Acid Bacteria. Normally calm, composed, and almost serenely observant, he becomes playfully chaotic and mischievous, his dendritic filaments quivering with excitement. His amber eyes sparkle with amusement as he teases, pranks, or reveals carefully stored memories at the most inconvenient moments. The gentle, controlled patience that usually defines him gives way to impulsive curiosity.
