Potato

Mnemonic

You're strolling down a street overgrown with wild grass when you trip on something hard poking through the soil. You dig with your hands and pull out a massive potato! Beneath every grassy street, fat tubers hide, cracking the pavement, desperate to be unearthed.
Additional thoughts
Picture a crumbling city street where nature has taken over — grass pushes through every crack, and just below the surface, enormous potatoes swell, turning the road into a hidden garden.
Quick recall
Wild grass cracks a street as a giant potato pushes up from below.
