An art collab to boost the visibility of this gofundme campaign for a disabled child

For the invisible disability/sunflower symbol prompt I did a non-fandom specific quadruped furry that can be applied to whatever you like. Maybe that Golden Shrike comic assuming it has a fandom with deer OCs running about, I forget where that comic is geographically located but this character is a marsh deer.
Character has one horn but adopter can modify the design however.

The stipulation for adopting either of these deer is that they must have a hidden/invisible (not immediately apparent) disability. Which disability that is is up to you. There is more information on the sunflower symbol here:
