Lily Pad

The Lily Pad is an aquatic plant that lets you plant non-aquatic plants in the Pool. It is based on the leaves of Nymphaeaceae, a flowering aquatic plant, better known as the Water Lily.

Usage
The Lily Pad is essential for any backyard level especially before obtaining plants that can attack zombies in multiple rows. Without it, the player cannot plant non-aquatic plants on his/her pool lanes and this will make the level difficult. Place Lily Pads on any water space you wish to plant a regular plant. Note that Potato Mines, Spikeweed and Spikerock can't be planted on top of a Lily Pad, but do not can other aquatic plants, like the Tangle Kelp and Sea-shroom. Cattails are the only aquatic plant that can be planted on top of it, because the Cattail is the upgrade of the Lily Pad. This Lily pad is can planted in non-aquatic plants.

Strategy
Wait until you've gotten your sun production started before placing Lily Pads, as aquatic zombies always take a little time to get started. When you do begin placing them, try to plan ahead for what you'll need. Don't put empty Lily Pads at the far right unless you absolutely need the extra time that Zombies will take chomping on them. They should be used to slow Zombies down, and as cheap and fast as they are, this might just save you in an emergency. Remember that Dolphin Rider Zombies will jump off their dolphins after leaping over a single Lily Pad, so use this to slow them down, but plant the Lily Pad in the second column as the zombie jumps over the first square of the pool.

Practically anything can be planted on Lily Pads, so if you actually run out of good strategies in a Pool game, just use the normal strategies you would use in the front yard, except with Lily Pads below it. For example, you can still plant Torchwoods on Lily Pads. Simply remember the plants that can't be planted on Lily Pads.(Spikeweed, Potato Mine, Flower Pot and Spikerock
