I need help coming up with a first birthday gift for a boy who is turning one and has everything! Looking for something different and would like to stay under ~$25.

He has an older brother (5) so also has his toys, plus combined they have every toy under the sun. I was thinking the Tomy Hide n Squeek Eggs and a board book but I don't know if that is enough considering they have big/loud toys. When DS turned 1 they gifted him LeapFrog Fridge Phonics, but I know they already have toys like that. Any other ideas?! Thanks!
