Query: Perfect for when you need a closed mouthed hippo around

I will agree with the previous poster, it is quite "non chalant". As if it's sitting there in your private marsh land area waiting to spring... waiting to become an Open Mouth Hippo Head!But, between the Open Mouth and Close Mouth, I still recommend the Open Mouth for pure bang for your buck.
