A lost key leads to possible new friendships—or at least a strange, short-term collaboration!

Dr. Zomboss needs help again! Mr. Stubbins, Zomboss’s best friend and zombie hedgehog, craves a vacation. Zomboss is totally fine with this but—wait, Mr. Stubbins is going without him? Sure, of course. Zomboss is totally, TOTALLY fine with this. While Zomboss is being completely cool and fine with this and definitely not throwing a tantrum, Tugboat steals the key to his Pop Smarts vault and drops it into Mr. Stubbins’s suitcase! If Zomboss wants to stress eat Pop Smarts while his friend is gone, he’ll need to get that key back—without disturbing Mr. Stubbins’s vacation! Award-winning writer Paul Tobin collaborates with the fantastic artist Christianne Gillenardo-Goudreau for a brand-new Plants vs. Zombies original graphic novel, with lavish lettering by Eisner-nominated Steve Dutro and stunning colors by Heather Breckel!
