• Uses Wandering AI behavior
• Immune to damage (damage method does nothing)
• Immune to buffs (add method returns false)
• Has 4 interaction states before leaving
• Drops a Pasty on 4th interaction
• Speed increases with each interaction (starts at 0.5f, increases by 0.5f each time)
• On 5th+ interaction, says “I'm late” and leaves with speed 3.0f

• Pasty Item - Food item dropped by hedgehog
