Aliasing whimsum → whimsun
Link to alias

Reason:

Spelling.

I also just realised that the implication of

whimsum → undertale

needs to be removed and replaced with the implication of

whimsun → undertale.

EDIT: The tag alias whimsum -> whimsun (forum #272718) has been rejected by @NotMeNotYou.

Just a little bump to notify of the change made to the OP, since I found that the implication also pointed from the misspelled name.
