Neon Mixtape Tour - Day 31 is the thirty-first level of Neon Mixtape Tour in Plants vs. Zombies 2. It is a Locked and Loaded level. Electric Blueberry is showcased. The first appearing zombie is always Hair Metal Gargantuar. After completing this level, the player receives a money bag.
The player should always try to take out the Neon Zombies by using Spore-shroom, as Electric Blueberry will target Neon Zombies, then zombies with special abilities first, and finally Hair Metal Gargantuars. Two columns of Sun-shrooms are more than enough to keep up with the demand. Therefore, sun production is not an important element for beating this level. Intensive Carrot should be used for reviving Electric Blueberry if it gets killed.
Another strategy involves only using the Sun-shrooms, Electric Blueberries and Intensive Carrots. All you have to do is plant a column of Sun-shrooms at the back, then you can proceed putting the Electric Blueberries. Use the Plant Food you get to instantly recharge the Electric Blueberry seed packets. Use the Intensive Carrot just in case you don't have Plant Food. Feed the remaining Plant Food to the Electric Blueberries in the final wave. With the use of this strategy, the difficulty may be lowered to medium.
- Excluding specific Piñata Parties, Neon Mixtape Tour - Day 31 and Modern Day - Day 16 are the only levels in Plants vs. Zombies 2 where a Gargantuar is the first zombie to appear.
