Short & Sweet:
* Peter Piper picked a peck of pickled pigeons.
* Pigeons picking pebbles.
More Challenging:
* Four fluffy pigeons flew to a fancy fountain, flapping their feathery wings furiously.
* A pigeon perched proudly on a purple pillar, preening its plumage with a pleasant purr.
Let me know if you want more! I can keep coming up with pigeon-themed tongue twisters. 😊
