Splink tends to keep to himself, rarely making a noise or a fuss.
He's one of the Underbiters I see the least. In fact, I've only spotted him twice. Both times it looked like he was floating, but that could be my imagination. He's so quick it's hard to tell. His shimmering green colour adds to the illusion as well.
Splink likes to eat things that 'make stuff go'. Keys, remote controls, the prongs on electrical plugs, and ON buttons being his favourites. He might also be to blame for mornings when I start my car and the gas gauge is somehow near empty when I know it should be almost full (of course, I have my suspicions that Yetch might actually be behind that).
I'm positive Splink is responsible for the switch on my air purifier suddenly not working. I swear I can hear his gurgly little giggle every time I turn the control and nothing happens.
