Sometimes - rarely - Jaby can be playing something else then Seamonstah - knight for example! Like he already saved Fyari from the dragon he now saves... well... He doesn't save Nic xD Instead they have a playfull fight! About... hard to say - but I'm sure both are convinced that they will win, because the hero always does c:
Yes, Jaby wears Schwimmflügel on his legs and has a inner tube (Strange name D:)
