Can Weird People in Strangerville Travel to Other Worlds?

I have a sim that lives in Oasis Springs, he went to StrangerVille and bought some bizarre fruit. He ate one and gave his 2 clones one. They all run around after midnight possessed and plant the fruits all over their neighbourhood. They do grow but only to the first stage and revert to a dirt mound on travelling or in the daytime. I have a couple in planters on the home lot and they act the same way as the ones outside.
