What happens when you have a goat do nothing but attack robots from age 0.02 until 1.1 Elder?

Lil Baphomet at age 0.15 having fun with 20 Iron Spiders. After about age 0.25 he started to 3 shot the spiders and we needed a new plan. Between 0.3 and 0.4 we fully changed to armored P4 units.

Elder Baphomet not 1-shotting detained P4 skeletons.

Besides killing a couple raiding Sand Ninjas (each attack launched a limb or killed), he didn't leave this building. How did he get 16 athletics and reach full speed of 21 mph? Athletics actually pops up for a split second during each attack.
