What is the plants motivation

It looks like the plants are trying to prevent a solar eclipse that could prevent them from growing again which is a pretty dark ending for this game.

plus the plants want to protect there daddy CCCCCCCCCCRRRRRRAAAAZZZZYYYYYYYYYYY DAvE

okay so in this game is self preservation?  what was in it GW1?  Sometimes I wonder if Dr. Zomboss and Dave are friends.  When I plant an enchanted garden ops Dave says he is phoning the zombies.  I wonder if Dave and Zomboss are just having fun together with this little war of theirs.

in gw1 the plants evolved and some of the zombies got smarter where they was able to use weapons

i dont think there has been a origins story yet of dave and zomboss yet.

but the thing is whats the gnomes part of this on going saga

well I guess its a mystery for the time being.

Seem pretty obvious they either want to protect humans (mostly crazy dave) or just themselves in some case.

Expect in zombaria then they just want to crash a party lol.

 Pretty sure dave saving that he will "phone the zombie" was just a another case of him shouting random non-sense as he often do.

I just think its weird that the plants want to protect the humans now, especially since humans eat plants.  In the first game (original PvZ) the plants needed the humans since they were essentially planted in the ground and were not sentient beings.  now the plants can take care of themselves, can run around, jump, make noises, etc.  When I go to Chomper's pizza the menu has plants for consumption as well as dirt and minerals.  This means that either the humans go to Chomper's pizza and eat the vegetables/seeds on the menu and the plants also go to chomper's pizza and eat the dirt/minerals.  OR the plants are the only customers and the eat the dirt/minerals as well as other plants (cannibals)?

Anyway I find it weird the humans want protection from the zombies because they want to eat them yet the plants would probably be better off siding with the zombies for two reasons.  1 the plants would no longer be eater 2 this would give the zombies more brains since the humans lose some protection.
