Pump is more cautious than Skid, but is also just as optimistic. Pump's gullibility also matches Skid's, yet his rare clever moments only seem to happen when his eyes turn cyan to warn others of upcoming danger. Just like Skid, Pump also enjoys Spooky Month, but despite his young age, it is possible that he has a dark-humored side, evidenced by him suggesting that he and Skid ignite a Happy Fella doll into flames to "see if it screams", and when he indirectly tells Moloch to snap his neck and kill himself. Pump is also caring too, This is shown when he got mad at the Happy Fella doll for getting him in trouble with his sister. He is shown to not hold grudges as well.
Speaks in quick kid-speak, lots of short statements and warnings. Eyes go cyan, so he blurts danger first, then apologizes. Uses playful curses when excited.
