Just keep two rows of spikeweeds maintained in the front, then let peashooters do the rest. This works great for the bobsleds and the zamboni machines!
1 Go into Last Stand with Coffey Bean, Marygold, Magnet Shroom, Gold Magnet, Wall Nut, Tall Nut, Water Liley, and then anything else you can get. You won't need them.
2 Set Marygolds everywhere for the first 4 rows than 1 of Gold Magnets, than Marygolds until the last 2 rows.
3 Then Put 1 row of Wall Nuts and 1 Row of Tall Nuts.
4 Start wave and keep repairing your nuts for as long as you can.
First you need coffee bean, doom shroom, lilly pad, marigold and if you have room, a gold magnet. Go to mini games and do last stand and plant marigolds all around except for 5 spaces. Plant one doom shroom [does not matter where] and 4 gold magnets press start wave then when a lot of zombies go near the doom shroom plant coffee bean on it and get all the money.
First, Choose sunflower, melon-pult, winter melon, Tall-nut, Imatator tall-nut, jalapeno, squash,
flower pot, and twin sunflower (if Nesessary). Roof Cleaners Are Strongly required. Plant 2 Rows Of Sunflowers. Then Plant 1 Colum Of flower pots, with tall-nuts on them. There is one colum of flower pots, plant melon-pults on them. Plant winter melons on the melon-pults.
This tip or trick whatever you call it only works in pool/day levels. All you have to do is plant sun flower in the top left coner. Get sun plant another next to it. And if any zombies come plant potato mine. Plant 4 sun flowers in the bottom left. Plant 8 lily pads. 4 next to the mower/pool cleaner make a space and plant the other 4. Plant 2 wall-nut on the last 2 lilies and make a 2-colmn of sun flowers and the rest of the space plant whatever you like. Hope it works!
