"Once, there was a scientist who studied long-eared jerboas. While he was working on an experiment, a jerboa that was on a table accidentally knocked over a beaker full of a rare acid, which spilled all over the floor. The scientist managed to save most of his jerboas, but some of them got lost, and their fur got coated in the acid. The fire eventually reached them... But it didn't kill them, or even hurt them! Instead, their fur burst into flames, and didn't burn off! It turned out that the acid, plus the flames, created a whole new species out of those long-eared jerboa! Unfortunately, only four of them were transformed into fireboa. But, they will reproduce! there are two of both males and females!"
p.s
"Nobody knows how they got their two black horns. It was probably the acid that caused it."
