Missing Trivalve

[Barushie]

So, i just got 2 blue trivalve eggs and i hatched them at my base in the artic spires, and i told them not to follow me and i worked on something else for about 10 minutes and when i came back only one of the two trivalves where there! i have no idea what happend, and i`m kinda histerical about it. there was a snow stalker nearby and a little wile away was some ice worm that is always stuck in the same place. can somebody please tell me how i can get my trivalve back?

Ice Worm ate it LOL. Although I don’t think that they can do that.

You kept them on land, which means they probably fell down in the water when the terrain didn't have its collisions.

Use the ghost command to check under the terrain, you'll perhaps find it there. Ask it to follow you and teleport somewhere in the water. Or spawn another one with "spawn trivalveblue".
