In 1020 A.D., Another World, Kid called Serge across the dimensions from Home World, as Serge is able to travel between them since he is absent from either one or the other at any given time.
Why is it, though, that Poshul is able to make the dimensional cross at this point in time, considering that he/she/it exists in both worlds and he/she/it has no access to the amulet at this point in time?
The only explanation I can think of is that Kid was actually at Opassa Beach in Another World and used the amulet to summon Serge across, which also misfired and grabbed Poshul. If so, though, why wasn't Leena pulled across?
