a leprachaun from Ireland who travels by rainbow with a pot of gold. He is half Russian, half Irish, and half Ukrainian. At first he liked unsalted pretzels, and now he likes salted ones. He likes freshwater fishing and always says "My friend said..." but never names them, as they may not exist.
He often travels to Cleveland, Ohio, and that is why he missed his astronomy research.
A: I'm going to Cleveland!
B: You must be Daniel Bratslavsky!
C: You went to Ireland? You must be Daniel Bratslavsky!
