My creature looks like a Psittacosaurus, with spikes all around its body, it hisses and uses its tail whip as a first. As last resort it will squirt an aimed stream of blood from its eyes toward its predator.
The blood only affects mammals (including humans) because it contains Capsaicin in high concentration (a compound that is found in chilli peppers)
My questions is:
Where can my creature get this Capsaicin, can it create its own or it has to get from a source (like its main food source that contains this subtance)? also how many times can my creature be able to squirt its blood to its attackers?
