error when living entity created

i am doing a mod that ads lots of mobs, but one fails, when i build there is no error but when i load the minecraft client, it crashes, i already made sure there are no repeated parts, and there are not non ASCII characters, other models made with the same program work perfectly but only this one fails.

english is not my first language and i don't know anything about java codding

here is the crash log:
