Apparently, this version of the PGL Shiny Tapu Bulu uses the wrong " ' " in the OT name Ula'ula,
and as a result, trading it will result in the OT name changing, not dissimilar to the Rally Mew.
When traded, it's OT will change to  "Sun." or "Moon." (with a period), based on language and game received in.
[Example, if it was received in a French game, it'll become "Soleil." when traded]
It is not known if this error would be fixed before the end of the distribution.
