I am a house without a door, Filled with songs you can’t ignore. Feathers flutter, wings will vary. What am I?

Although usually quite small, I can make a whale of a meal. I wander the oceans, one of the largest of my type sound like they would pair well with a peanut butter spread. Start with the type of location your are developing in the game Ark Nova, followed by a position you hold in an isometric exercise. Finish with the singular of something of which adult blue whales have more than a one hundred.

Oh my stars! As still as a whisper in the ocean's hold, a giant's crown of icy cold, beneath the surface, secrets unfold.

Where engines rest and feet find leisure. A patchwork quilt of green, open fields where laughter is the wind's song. Kids play and pets on leash stay.

Stress my ending and I will leave without a care. Stress my beginning and nothing will grow.
