You could get about 8 bits per animal, and 5 bits per hand-written verb / adjective / place (32 choices per category). So that's about 7-10 words you need in the frame.

You could get decent entropy with: the {adj} {adj} {animal} {verbed} the {adj} {adj} {animal} from in {place}. That's 5+5+8+5+5+8+5 = 41 bits.

I'm just wondering if it's worth it.
