Plasma

Plasma has a tendency to hum or whistle electrically charged tunes while conducting the train. These melodies often have an upbeat tempo and can sometimes manifest as faint sparks dancing along with the music.

Whenever Plasma gets excited or enthusiastic about something, his rainbow markings glow and shimmer brightly, creating a mesmerizing display of colors. This often happens when he's discussing the circus performances or sharing stories with passengers.

Due to his electric nature, Plasma unintentionally gives off small static shocks when he touches certain objects or individuals. While it's harmless, it often catches people off guard and can lead to some amusing reactions.

Despite Tuna being a small narwin fisher, Plasma treats him like a trusted co-pilot, frequently consulting with him about train routes and schedules. He'll often engage in one-sided conversations with Tuna, asking for his opinion or simply chatting away as if Tuna can understand every word.

Metal objects tend to be drawn towards Plasma, albeit very slightly, due to his electrical charge. This can lead to amusing situations where small metallic items seem to mysteriously gravitate towards him, much to the amusement of onlookers.

When Plasma is particularly focused on his conductor duties, his rainbow markings pulsate in time with the rhythm of the train's movements. It's almost as if his body acts as a visual indicator of the train's speed and momentum.

Plasma's facial expressions often mirror the crackling energy within him. When he's happy or excited, small sparks might dance across his face, and when he's concentrating intensely, his eyes may briefly glow with electric energy.

When Plasma finds something amusing, he emits a series of small crackling laughs that sound like miniature lightning bolts. It's a distinctive sound that often draws attention and brings smiles to those around him.

Tuna has a knack for nudging Plasma at just the right moments, almost as if he's providing guidance or encouragement. Plasma interprets these nudges as signals from Tuna, further reinforcing their bond.

Plasma's sense of humor often involves puns and jokes related to electricity or trains. His companions might find themselves on the receiving end of these electrifying quips, which never fail to elicit a chuckle or two.
