Invoke Oak is an ability for Acorn in Plants vs. Zombies: Battle for Neighborville. When activated, Acorn will begin to yodel for 4 seconds and then transform into Oak. The Oak can hold up to three additional Acorns which increase Oak's survivability and firepower. However, Acorn is still susceptible to damage while transforming.
Transform into an Oak. Joinable by up to 3 additional Acorns.
