dr zuna is the cute and adorable goggle wearing four armed fluffy and soft tail moth mad scientist of our castle more specifically an entire lab facility underneath our castle~

they love studying inflation such as p balloons pear balloons blimp fruits and how we are able to overinflate ourselves to critically dangerous sizes~

of course dr zuna is very smart but theyre also very clumsy and oblivious sometimes when it comes to distraction like how he wanted to test fezzys overinflation limit before he pops by inflating him with a overcharged electric pump and was trying to find his pen but it was in their other arm and fezzy ended up popping and dizzy but dr zuna still got the results~
dr zuna also fell into their supply chamber of inflating liquid where they were inspecting the gas from the liquid and overinflated and popped painfully shattering the chamber they were in and causing a massive mess everywhere in their lab that took a lot of time for them and the lab to get cleaned up including dr zuna to be stitched and bandaged~

dr zuna still has their mad scientist profession and always has the answer to our questions usually~
