Plantelopes

Plantelopes living on Mars travel around in big herd on the surface, but are totally harless to the adventurer, since they are peaceful. Only in case of provocation do they attack, and this VERY fast!

Lore
''The gazelle-like plantelope may remind explorers of its smaller cousin, the jumping bean. Normally docile, it tends to be shy, choosing to flee rather than fight in almost every case. The plains are its customary feeding grounds though herds of plantelope have been seen leaping goat-like in the mountainous areas of Mars.''
