She costs 1 sun and when a zombie approaches her, she will push them a certain distance back, as well as all other zombies within her range. She will then disappear after one usage, unless promoted with a taco.
Her name is a portmanteau of "Pushy", referencing her ability to push zombies in her lane back, and "pussy willow", the plant she's based on.
Note: The stats shown below only apply to Level 1.
Plant Food effect
Pushywillow's Plant Food ability is named Fuzzy Fury, in which Pushywillow will push all zombies in her lane back, as well as all zombies in the two adjacent lanes above and bellow her. Fuzzy Fury can be further upgraded to allow Pushywillow to stun zombies that are pushed back.
Pushywillow's Tacobility is named Buddy Up. Which allows Pushywillow to remain on the lawn after usage, allowing her to push more zombies at a time.
