Number of animation frames to use for walking/running Mario, indexed by Mario's status.
Ex: db $01,$02,$02,$02 The first byte it for small Mario, next is Super (Big) Mario, then Cape Mario, and finally Fire Mario. $01 means 2 frames for small Mario and $02 means 3 frames for the others. Longer animations are possible, but that'd require moving stuff around in $13E0, which hasn't been researched yet.
