You cannot specify the deadmau5 player model for a mannequin

Java Edition has three distinct player models:

• the wide model

• the slim model

• the model with ears for deadmau5’s account

When summoning a mannequin, you can choose which model it uses. “wide” and “slim” both work, but there does not appear to be any way to select the third, despite it being an actual player model.

Example command: /summon minecraft:mannequin ~ ~ ~ {profile:{texture:"minecraft:entity/player/wide/steve",model:INSERTMODELHERE}}

Replacing “INSERTMODELHERE” with “wide” gives the wide model and with “slim” gives the slim model. However, there does not appear to be a way to get the third model: neither “ears” nor “deadmau5” work, and I can’t think of what else would.
