[HoMM V]9 Race - Swamp! Is it needed?

or maybe not a snake, but some kind of gadfly or blood fly, like the ones in Gothic, they would definitely fit in 1 cell... or here are some more suggestions: make a jellyfish that occupies 1 cell (like in Disciples 2) make a snake that occupies 4 cells, or make it look like several snakes connected/fused together by their tails...
