If you see it and are with a member of the tribe, use a rope to tie that tribal member up and run...

When a high lever gigan found your house . Let your tribe and run fast as you can

Me and my brother ride dire wolfs to go to the clever cave all crashed join back my brother see gigan

We run like a moschop

I just tamed a gigan lvl 33 but now he stucks in a ice rock and cant move anywhere
