In BFB, Nickel seems to be far more erratic than in previous seasons, sometimes spouting nonsensical sayings and phrases. He also cannot easily tell when someone's being sarcastic. Nickel retains his happier personality in BFDI:TPOT, even returning to his erratic phrases, though he can still get easily frustrated when pushed, like when dealing with the Singing Narrator. Nickel seems to be much more happy-go-lucky than he was previously. He has no arms, only legs. He's absolutely adorable, too!!!
