Ninjimp (忍者小鬼僵尸; rěnzhě xiǎoguǐ jiāngshī) is an Imp variant that encountered in Heian Age in the Chinese version of Plants vs. Zombies 2. He will appear either by his own or being thrown by Shogun Gargantuar. He throws a pufferfish at plants two tiles away from it, dealing 250 damage to them. Splitting Stephania is the main counter for this zombie, as she can bound back pufferfish projectiles that deals 125 damage to a zombie.
Ninjimp also appear from the "Airdrop Incoming!" surprise attack. If the smokebomb lands on random tiles and explodes into smokes, Ninjimps will spawn from targeted smokebombs.
Ninjimp is based on a common ninja and there's a similar trait to this zombie, which is his smokebomb surprise attack. The smokebomb surprise attack references how common ninjas use it as an ambush or when they're trying to escape from any attacks.
Ninjimp is a regular Imp that wears a brown ninja suit. He also wears a brown bandana with a metal sign in a middle with a letter "Z" on it (implies that it stands "zombie"), brown handkerchief, and brown belt with two sacks of smokebombs. And finally, he wears two white socks and two brown sandals.
He also holds a pufferfish on his hand. If the pufferfish being thrown by Ninjimp, the pufferfish will start inflate itself, like any real-life pufferfish do.
The pufferfish Ninjimp holds is no ordinary pufferfish. The spikes, they're real.Ninjimp often uses smokebombs to tell everyone, there he comes!
Ninjimps shares many similarities with the other Imps from different time periods. As such, he can be easily dealt with just like them. If they appear via the Heian Age's ambush, planting a Blover just when the message appear can blow them off the lawn, killing them. Alternatively, they can also be shrunken into oblivion via Shrinking Violet or stopped with Imp Pear by itself or its plant food effect.
However, Ninjimp is more dangerous to deal with than most Imps due to his pufferfish attack, which he can use every 3 seconds to instant-kill the frontmost plant if it's not a defensive plant. Fortunately, Splitting Stephania, a plant giving in the Heian Age can be used to deflect the attack back at Ninjimp. Infi-nut can also be used to stop his attack.
