Disney has been removing its focus on Mickey Mouse over the years as (I speculate) it knows at some point the mouse will be part of public domain, so it's been going on an IP shopping spree for most of the 2010s.
Mickey is still huge as the peer comment states. Mickey shaped beignets, Mickey hats, Mickey costumes, etc. Just that everything else grew up to have as much, if not more, brand equity than Mickey.
