He has a childlike personality and he enjoys the sight of nature. He is also very sensitive, which is shown when he becomes incredibly upset when Duck murdered a butterfly. He doesn't seem to be intelligent when compared to his two friends.
Instead, he is someone goofy, clumsy, stubborn, and gaunt, as he called Shrignold a "little baby pigeon", called his father a computer, and cut his finger with scissors in Death to see if smoke would emerge like Duck did.
However, in the 6th episode, he realizes something is wrong and constantly tells the lamp to stop singing. He knows everything that happened in all previous episodes and even recognizes the past teachers. When you were in the living room, Yellow Guy walked in and sat in his chair.
”Oh hello!! A new friend…? Hehehehe, hello, hehehe!!”
