Dropped napkin in air filter hose

I was changing my air filter by myself for the first time. I got the dirty air filter out and noticed underneath the filter was dirty as well, so I was trying to wipe the box out with a napkin. The napkin fell into the hose that's not going to the engine but its the hose under the battery and the air filter box. Please advise me what to do next, I feel stupid and don't know if this problem need immediate attention.
