Be aware that with so many animal mods, some mobs might repeat. Example: there is a mod called Rats, which adds helpful rats, and a mod called Mo' Creatures, which features a rat mob. These rats will act differently. HWYLA shows the mod which each mob is under the name, so make sure to use the features that correlate to the repective mod mob (tongue twister). Let me know in the discussion thread if there is a conflict between mods I was unable to catch.
Beginner Tips: Start a mob grinder as soon as possible. They shouldn't be too hard to find. Experience is used early on for leveling up skills and it provides a safe way to kill blight mobs, which drop heart containers to gain more health.
