Walrus Zombie

Walrus Zombie (海象僵尸; pinyin: hǎixiàng jiāngshī) is a zombie encountered in Frostbite Caves in the Chinese version of Plants vs. Zombies 2. Ski Zombie uses Walrus Zombie as a slope to jump past the player's plants. The Walrus Zombie also creates paths that speed up the aforementioned zombies, similarly to Zombonis and Zombie Bobsled Teams.

Almanac entry
体力耗尽后会趴下来休息.

海象僵尸一直对自己的体重不满意，于是它给自己制定了一个计划：每天跑步五公里. 可是当他开始实施这个计划的时候，他发现自己忽略了一个严重的问题：他没有脚……没有脚怎么能跑“步”呢？他想了很久也没有解决这个问题，于是他决定在没有解决这个问题之前无限期搁置这个计划……

In English
TOUGHNESS: Dense

SPEED: Speedy

Lies and has a rest while being exhausted

Walrus Zombie has always been dissatisfied with his body weight. He gave himself a weight loss program: run 5 kilometres a day. But when he tried it, he noticed a serious problem: he has no legs, so how can he "run"? He thought for a long time and did not solve the problem, so he infinitely postponed this plan until he solved this problem...

Strategies
This is a very dangerous zombie if it is let into your lawn far enough. It will move and crush all plants that are in it's way, then will stop at a certain point. It will also create ice trails, so the player cannot plant behind it. After it stops, Skiing Zombies will appear and jump over it, jumping 5 tiles ahead of the walrus. If it is allowed to stop at the 5th column, the Skiing Zombies will reach the last column of the lawn and will very likely make the player lose. Whirlwind Acorn will kill it in one hit, while Magnifying Grass will kill it quickly. Sliders will make this zombie stop, but they do not stop Ski Zombies from breaching your defenses. Hypno-shrooms on a zombie that is ahead of it will kill the walrus easily as the walrus will do nothing.
