Ammo(
) was a type of collectible item released during the Treehouse of Horror XXV Event. It was used to shoot down the Rigellian UFOs that were seen flying around a Neighbor's Springfield. Ammo could be collected three different ways: it had a small chance of being dropped when tapping on Rigellians or Grem-Aliens, it could be bought in the store, or it had a small chance of being in the Treat Bags. The Ray Gun, even if owned from previous Events, would also spawn 1 Ammo every 8 hours.

Rigellian UFOs[edit | edit source]
Rigellian UFOs had a 25% chance of spawning in Neighbor's town, and it could only be shot down using Ammo.
Odds[edit | edit source]
When UFOs were shot down, they yielded prizes varying from the treats found in Treat Bags, to the Treat Bags themselves, to even a chance of getting Donuts.
