First four can be thrown or kicked And on the court can be bricked All together, a pin will pop! Add water and drop.

I am small, prickly, and come with many. Worn on legs, sometimes on arms, my siblings and I are here to protect our wearer. Lose the first and I'm large, lethal and come in pairs. Worn on heads, sometimes on noses, here to be a weapon and protect our bearer.

I have a mouth but never speak, a belly full but never eat. Letters and packages are my daily treat, what am I?

I am two letters, an abbreviation, you see, In a hot climate, you can't go without me, Through latent heat I work tirelessly, Turning ambient temperature into a cooling breeze

Hidden in a shell's embrace, a treasure from the deep. A moonlit drop of ocean's grace, where secrets softly sleep.
