spinning head after body swap

I body swapped Poppy and Clementine earlier today and when I checked back on them, Clementine’s new body seems like I have the head placed on loose. By loose I mean one little push and the head can spin around completely lol. Is there something I can do to fix this? First body swapped and would love any tips or trick for next time as I’m also planning and doing an eye swap with others. TYIA❤️

Edit: SWIVELS!! That’s the word I’m looking for. The head swivels
