The golem is now fully occupied by the blue pony again and will shoot at her soon. You are right behind it.

Jump on the golem's back.

Buck one of its legs to imbalance it.

Strict Mode (In Strict Mode, the game will not show you options that require a skill you do not have. In non-strict mode, these options will be greyed out but you can still cheat and access them. You can switch modes at any time.)
