easily doable by 4 bsts
each pop a CC, wait 1,5-2 mins for bst timer, and let CC do his job on the big spider.
You'll need 2 CC's each.
After Anansi dies, release, and charm the first 4 sons. Send them at the rest.
At last, let the sons release 1 by 1 to finish them off.
Takes maybe 10-12 mins total.
