I was about to complain that this safari was only giving me lillipups and after I said I didn't want lillipups it wasn't giving me anything, but finally something sparkled and it's not a freaking lillipup.
It's a blue-striped kecleon. Female, timid, takes plenty of siestas, with Color Change. Appeared after 10,033 REs
Much later edit: Had to do some pruning of my friends list since adding Kyuu filled it completely, and I ended up back in the dunsparce/minccino/eevee safari for a while. Found a shiny there, but thankfully it wasn't another minccino. It was a pink dunsparce. Female, modest nature, alert to sounds, with Serene Grace. Appeared at 10,549 REs
Edit #2: First shiny from Kyuu's safari is another dunsparce. Male, adamant, alert to sounds, Rattled. This one appeared after 11,452 REs
Edit #3: Shiny dunsparce #4 after 11,502 REs. Male, timid, capable of taking hits, Run Away.
Wonder Trade is gonna love me when I get everything back to Ultra Sun
