If CHIPPIE is slain physically, e.g. by GLAIVE, you can resurrect it with DEATH'S REMEDY, that it might be lured to the TABLE for SACRIFICE.
It is a little "tricky" to lure the CHIPPIE over, you need to hold SEEDBAG and have some SEEDS within. They will follow you to the TABLE.
I'm glad you're enjoying it, there's much to do crammed into HG3!
