The tag alias #75796 chu_chu_rocket -> chuchu_rocket is pending approval.
Now properly as an alias. 🫠( See topic #55788 / implication #66975 )
Reason: The official title seems to be ''ChuChu Rocket!'', so I think this is the version that should remain.
(At least I now know the site asks for confirmation, when rejecting an implication/alias/BUR. I was afraid of accidentally clicking that button)
