In this specific case,i have no problem with it.The thing is the size of a house(so will not fit in a house),has DPR of 3rd level character and...well,it's a pile of hitpoints.
At least it's not COMPLETELY useless like that silly zombie from a ring.If only there were two...then at least you could've use them as backup dancers.
Update:i've been told how to make two zombie back-up dancers with that ring.I withdraw my complaints.
