Due to its lack of any strength and its low health, Lil' Buddy serves its purpose as a weak shield against zombies, and it could save an expensive/valuable plant.
It can be used with Spineapple to make this a one-time damager. Alternatively, it can be used as "cannon fodders" for Briar Rose when it is used with Wall-Knight to help destroy a powerful zombie. If they survive a turn, Template:PvZHLink can be used to heal the plant hero.
Against
This plant will just block attacks. As long as it isn't boosted, any attack can destroy it. If you have zombies with the Frenzy or Strikethrough traits, using them will allow you to both destroy the Lil' Buddy and attack the plant hero.

Trivia
Despite being called Lil' Buddy, it actually resembles a poppy fruit rather than a poppy bud.
It is one of the only two seed cards in the game. The other is Seedling.
Coincidentally, both have 0 strength and 1 health when played.
Its description references the fact that it has the Team-Up trait.
Its description is grammatically incorrect, as the description is a quote from Lil' Buddy, but has no quotation marks.
The attack it does is similar to the attack from Pair of Pears, which involves it firing seeds.
