These things could theoretically make short work of most other iconic Doctor Who villains, so it’s a shame the Doctor can’t capture one to use when things get rough.
That said, this Doctor seems even more against killing others than past incarnations were, so she may not use one of these adorbs killing machines even if she could.
Regardless of what Ptings are or aren’t, it’s exciting to imagine how Doctor Who will utilize the unique species in the future, assuming the show can keep using the CGI-heavy effects needed.
