Insomnagranate

Insomnagranate is a plant in Plants vs. Zombies: 2, and upcoming in Plants vs. Zombies: Realms. It fires seeds that penetrate through zombies in its lane. When it is eaten, it explodes, causing all zombies adjacent to it, or next to it paralyzed. That is because they are asleep. It is permanent for regular zombies and coneheads, but for Gargantuars and bosses, it is not. It is only temporary.

Strategy
This is a pretty over powered plant with normal zombies. It is very good with other plants, especially in other lanes next to it. When zombies are eating the plants, and Insomnagranate explodes, the zombie immediately stops eating the plant. This is very useful. However, the plant that got eaten stays with the amount of health it has remaining. Overall, this is a pretty unique plant that is very useful in battle. It does not affect Gargantuars/Bosses/other zombies other than Normal and Coneheads, but makes them sleepy temporarily. Bosses only last 8 seconds, Gargantuars last 10 seconds, other zombies last 20 seconds, while zombies/coneheads last for a minute or so.
