Navel Laser is an ability for Citron in Plants vs. Zombies: Battle for Neighborville. When activated, Citron has a brief animation where he turns his triple shot weapon into a lance shaped weapon, then starts shooting a laser for 6 seconds. This laser starts off doing 5 (6 headshot) damage per hit, and increases to 10 (12 headshot) and then 15 (18 headshot). The visuals of the laser change slightly to indicate this.
A precision beam that grows in power.
