Smalls

basic character
smalls is one of the bronx newsies seen mainly in the song brooklyns here. in most productions of newsies smalls is also shown as part of the manhattan ensemble. the majority of the fandom sees smalls as a female but many actors that have played smalls in newsies run at paper mill and broadway have disagreed about their gender.

smalls is shown to be upbeat and easily excitable, being the one in every official production of newsies except newsiesLIVE to shout 'so is the bronx' at the end of brooklyns here.

though they are an ensemble character they do have a newsiepedia article you can find here

personality
like previously stated smalls is easily excitable and hyper. they seem to be one of the younger newsies, and liana hunt in a meet the newsies video mentioned them being in a family of all boys so it would be easy to assume smalls is used to rough housing and being in a rowdy environment. they are the one who holds up the sign in brooklyns here (in every production except for newsiesLIVE) leading many to believe smalls is the leader of bronx but that is up to speculation.

meet the newsies (liana hunt)
for one of the canon sources of information you can look to the meet the newsies video for liana hunt where she talks about her take on the character smalls and being kathrine pulitzer as well (smalls information starts at 0:49)
