Piddle is crying with an ear-ache

I can't find his eardrops and my parents aren't home at the moment, and my mom usually knows where they are. I have searched everywhere! They could be gone.

Is there anything I can do until they get home? I have tried whiping it out with a tissue, should I try a Q-Tip?

Also I know that when my mom has an ear-ache she uses olive oil(I believe?), would that be safe for him?

Thanks
