I have a new idea for plants in PvZ hero's. One, tangle kelp, it could be like the potato mine, but for water. It could be a Guardian class plant that costs 2 sun, have 1 health and have amphibious, but instead of doing 2 damage, it could do 4. But it must be placed on water like the real thing.
My second idea is lily pad. Instead of it being a plant it could be a trick, it could be a Guardian or Mega-Grow class. It costs 4 or 5 and says "give a plant amphibious and move it to the water."
and last but not least, pitcher plant. It could be the amphibious version of the prickly pear cactus. It could have 6 health and have 0 attack. But it's affect is "when this plant is hurt, do 2 damage to a zombie here"
i love the PvZ genre and I hope you guys get rich off you awesome games. I know you guys are working real hard on improving you games, but if you read this, if you need another idea, here you go.

Those are really good ideas, although for Tangle kelp I would make it -3 damage or make it cost more. 4 damage for 2 sun is OP.
