Following a good soak in Zelda 2 dialogue, I think I've cracked the code to writing pithy, enigmatic fortune cookies. Just write very simple, literal ideas out in short form, rearrange the sentence components to somewhere between "Normal" and "Yoda," and omit the occasional article. Here are a few tries, with a Zelda-inspired one for starters:
"In dark places use candle to light the way."
"Find important objects underfoot."
"Here and there discover enjoyment."
"Your attorney works hard to bring you good news."
"Do not allow cat and dog to be unsupervised together."
"To help flowers grow use the hose."
"Pedestrians know what motorists choose to ignore."
"The grasshopper does not sing what will happen next."
"Do not look away in frustrated silence."
"The cookie is only a guide to fortune. Like the moonlight it has little to say but will show you what is already in reach."
