To be fair, it's never been a concern with any of the past Space Hamsters. And it's not like it was a huge story spoiler.
At the moment there doesn't seem to be any similar situations coming up to worry about, so this particularly mischievous hamster is probably a one-off.
And having Nene's revealed form is fine. It'll be nice to have in the collection and usable as a wallpaper for the phone. 🥰
Don't worry too much about it. You've already got a fix in mind that'll resolve it. Keep up the good work! 👍
