Big Wave Beach - Day 7 is the seventh level of Big Wave Beach in Plants vs. Zombies 2. The tideline in this level is located before the first column, which means that the tide will rise, and water will cover the entire lawn at one point during the level. After completing this level, the player receives a money bag.
In this level, the tides can reach up to the first column. Therefore, the player must use Lily Pad before planting plants.
The small number next to the zombie icon means that zombie will always appear in that lane, with 1 being the topmost lane and 5 being the bottommost one.
Make sure you have a Tangle Kelp at your disposal, or if possible, an Imitater Tangle Kelp as well, as due to the tide reaching the first column on the right, Snorkel Zombies can possibly be fully submerged for the whole level, rendering most plants useless against them.
In addition to the above, the Wall-nut, Tall-nut, and Infi-nut can come in handy as they will halt all zombies and weaken the Snorkel Zombie by forcing it to surface.
Begin planting lily pads as soon as level starts. The tide does not reach the first column until the end of the round, but will start flooding over columns to the right somewhat fast. If you plant a plant and there is not a Lily Pad under it, plant one immediately so it does not get destroyed as the tide gets closer to your house.
