Help!

So we are trying to get Henry to eat some finger foods. It is not going well. I have been feeding him chunky food from a spoon for a while so I know the problem is not that he can't eat it, he just doesn't want to. He loves food so I don't know what the problem is. When I put things down on his tray he just moves them around and looks at me like what is this. I know he can pick it up because he picks up the smallest things he finds on the floor and puts them in his mouth! So far I have tried cottage cheese, puffs, and Cherrios. Any advice on getting him to eat finger food?!?
