Castle Gate Zombies

I recently did my first Halloween Festival, I was awarded 5 Zombies which came with my King on Offense,

but I am noticing that some players have Zombies in their Defensive waves, and I am unsure how this happens;

and more interested in how I might get them for my Castle Guard

Trioxin Tower, the Pro-boost for Snake Towers, makes them spawn zombies

 

 

Yes and if you have 4 of them as gate towers, they will all spawn in the middle at nearly the same time. Way more deadly and annoying than having basilisk towers at the end. Nearly impossible to approach and survive to tell about.

ok thank you all for that, I have 2 snake towers, so if and when my Alliance gets this boost I will have some zombies, I will place my 2 snake towers near the castle gate :slight_smile:
