Infi-nuts are weaker than Wall-nuts, but will regenerate over time.

TOUGHNESS: Elevated

RECHARGE: Mediocre

As young nut he spent way too much time standing between two mirrors and trying to look into infinity.

Plant Food Upgrade
Infi-nut's plant food sends a force field across the lawn adding an extra layer of defense to your lawn. The barrier can last for a long time, but falls after a few hits (amount of hits unverified). Very useful against Imp Cannons as it makes imps fall into water if its placed at the edge.
