Spider Lotus

Spider Lotus is the third plant of Viking Reign in Plants vs. Zombies 2 and the Dimensional DLC for it along with being the third non-catapult plant in it. However, it is the second non-catapult plant within it when only considering the second part. It is slightly unique in the fact that it's exclusive to iOS devices in the International version. In a 3x3 area, spiders (normal or special) appear. They then crawl forwards and damage any zombie they pass. However, if the spider has another ability, it will also do something else. For example, a Burn Spider will burn and damage zombies. It's android counterpart is Nebulactarine.

Powered
When powered by Moonflower, spiders summoned by Spider Lotus can either go forwards, backwards, downwards or upwards. The direction they go depends on how many zombies there are in that direction. If there are no zombies in a certain direction, they will not crawl in that direction. The less zombies there are, the less likely spiders will target them.

Strategies
Don't use it as your primary attacking plant. It can be useful against Blacksmith Zombies to vanquish it, disabling the usage of the anvil. However, the anvil would still be an obstacle, therefore another plant should take it out other than the spiders. The Round Shield Zombie can pose a threat, as the spiders are blocked by the shield. On the other hand, they're alright against other zombies.

Plant Food
Spider Lotuses are more likely to summon special spiders than regular ones. If you want to see the exact changes, see the "Spider Types" section of this page. This is the only permanent Plant Food ability to not change the plant's appearance.
