Good Morning

Strategy
Time to restart Adventure Mode! Crazy Dave's going to put in three plants, so ignore those, except of course a Coffee Bean. Pick the Sun-shroom, Puff-shroom, Fume-shroom, Gloom-shroom and Hypno-shroom to beat it. To get it, only use Mushrooms and Coffee Beans. You are allowed to use an Imitater (for mushrooms only). Refrain from planting any other plant or you won't get this acheivement. Put in three Sun-shrooms and wake them up and later, if you have enough sun, yothumb|300px|right|Another Strategy Guideu can buy two Gloom-shrooms. Puff-shrooms can help slow down the zombies (do not wake them up as this will waste sun). Then, when a Flag Zombie comes, block the leader with a Puff-shroom and when they kill the zombies, you'll get an achievement.

Also, this achievement will still count if you complete ZomBotany with only Mushrooms and Coffee Beans, but that seems hard as there are Wall-nut Zombies (see the strategy in the Wall-Not Attack page).

Another strategy is to start off with Scaredy-shrooms in the first column, spam Puff-shrooms and their Imitater counterparts in the fourth and fifth lanes to keep the zombies busy. By relying on the sun that drops down occasionally, you will eventually save up 100 sun. Plant a Scaredy-shroom and a Coffee Bean in the lane in which the first zombie appears. Keep repeating this strategy for the other lanes. If you have sun to spare for sun-shrooms, then plant them but remember: Puff-shrooms are not for attacking! (In other words, no Coffee Beans for the poor little guys.)

Another strategy is first plant three Sun-shrooms to wake up later spam puff-shrooms to slow the zombies down, then use scaredy-shrooms to kill them. Put fume-shrooms in row 2 and 4 and upgrade them to gloom-shrooms for extra defense. This should be enough to hold up your defense.

If you fail with those 2 strategies, try this. Use the following:

Sun-shroom

Puff-shroom

Fume-shroom

Coffee Bean

4 random plants.

Put a column of Sun-shrooms near the Lawn Mowers. Put Puff-shrooms near the Sun-shroom column. Put a column of Fume-shrooms next to the Puff-shrooms. Use Coffee Beans on all of the mushrooms, and test the day mushroom attacking group kill the zombies!

Note: Completing a Pool or Roof level using only mushrooms and Coffee Beans does not count towards this Achievement, since it is not a Day level, and if you complete a Pool or Roof level you must also plant Flower Pot or Lily Pad

Trivia
