Beat the game, and then reach level 4-10 a second time. (both on the same file.)
The Yeti Zombie
sqash
No you cant I am very sorry
you get yeti zombie at 4-10 after you beat the game one
you unlock the yeti zonbie and you get a gold trophy
You get the yeti zombie after completing level 4-9 for the second time.
You cannot (well, if you're playing plants vs zombies, beat all levels twice, however)
It is on level 4-10 when you play it a second time once you beat the game
You must finish the game and at the very end level and there will be the boss with an extremely high shield. If this is not the one, the other one you find on level 4-10 (i think) on your second time round in the game. it is a Yeti. for more information go to youtube and type in yeti zombie-plants vs zombies. Hope i helped :)
finish the game once and on the second playthrough he will show in 4-10 level
plants vs zombies
Plants vs. Zombies happened in 2009.
