Repeater

Repeater is a peashooting plant appearing in both main series Plants vs. Zombies series games and spin-offs. It costs 200 sun, and fires two peas at the same rate as a normal Peashooter.

Origins
Like most other pea-shooting plants, the Repeater is based on the plant Pisum sativum. Repeater's name is related to the term repeating rifle, a rifle that incorporates the reloading and re-cocking actions into a single lever. Its name also refers to the fact that it shoots two peas at once, A.K.A repeating itself, and repeats its own speech in Plants vs. Zombies 2's almanac entry. It's name also has the word pea in it, referring to how it's a peashooting plant.

Plants vs. Zombies
Repeater is obtained after beating level 1-8, and is the last non-mushroom plant received in the Day stage, along with being the last plant obtained in the Day stage. It can be upgraded to the Gatling Peafor 250 sun upon purchasing from Crazy Dave's Twiddydinkies for $5000.

In Beghouled and Beghouled Twist, Repeater acts as Peashootereashooter's upgrade, costing 1000 sun. A reverse version of Repeater appears in the Vasebreaker mode starting with To the Left, functioning identically to Split Pea's back head.
