You're thinking of Reaper Bird, whose attack box utilizes that weird figure called "Everyman." If you look at the infobox on Reaper Bird's page, you'll be able to click a button to show a picture of Everyman.

I took a quick look, and while it isn't easy to tell, the dolls actually are not the same. You can just barely make out long, floppy ears on the dolls (akin to Asriel's and Toriel's), which Everyman does not have.
