Ice spider variant for Ice and snow biomes

A spider variant that lives in ice and snow biomes with a 
frosty snowy appearance and cold blue eyes.
 It would be exactly the same size and strength as a normal spider.
 But then there's also a boss ice spider which is huge and much stronger

that lives in a large ice cave with
huge icicles hanging from the ceiling.
The boss ice spider can summon ice spiders and freeze the player,
making them barely able to move or see. There might even be a boss meter
for the boss ice spider. So, to summarize, there would be the new ice spider,
the new boss ice spider,
a huge ice cave with giant icicles from the ceiling and floor, and new attacks.
This is my cool Ice Spider Idea.
