Wall-nut First Aid returns in Plants vs. Zombies 2 as an upgrade. This time, it is obtained after beating Wild West - Day 15 instead of paying coins. It retains the same functions as in Plants vs. Zombies, although it cannot restore the armor created by Wall-nut's, Tall-nut's, Pea-nut's, Endurian's or Primal Wall-nut's Plant Food ability.
