I'm squishy

Cailan had a pancake today with some syrup in a tiny bowl to dip his pancake strips in. When he was done he said "I'm done eating. I need a mopper. I'm all squishy."

Chris and I both asked, "You're squishy?"

Cailan said, "What am I from the syrup?"

I replied, "Oh, you're STICKY! I'll get a washcloth."

It was interesting, I've never seen him not able to find the right word before.
