A SPONGE
A sponge is something that has allot of holes, but can still hold/soak up water.
Because a sponge is an actual living thing in the ocean, which pulls in water through tiny holes, then spits it back out, as with household sponges sold in deaprtment stores.

When a sponge is submerged in water, the water enters the sponge through the tiny holes in the sponge. The sponge fills up with water, as a balloon fills with air, only not as visibly. When you squeeze the sponge, the water exits that sponge through the tiny holes...exactly the opposite of how it entered! Tada! :)
