I am a keep by the sea, I have no King, I can be grand or small I am built by many, but temporary What am I?

A package with love, from Denmark it will come, a gift for a child or an adult nerdy and mild. If left on the floor in the middle of the night, your foot will be sore from a small bloodless bite.

I can help to grant permission Or I’m how something quickly leaves your grasp I’m where you start your boating mission And a grip that didn’t last.

A woman's name, a colour, a tree and a cocktail ingredient. Reversed, it is a bad letter of the Alphabet.

I’m soft and I’m squishy, I don’t make a peep, but I may be nearby when you’re drifting to sleep. No heartbeat, no breath, yet I’m full of love, a cuddly companion is what you’re thinking of.
