Dear Doctor (Or whoever gets this letter)
First note: If you are not "The Doctor", this letter probably won't make any sense. Please replace this letter into the envelope and deliver it to The Doctor (If you know who they are. If not, just put it back where it was found. Or respond. Whatever feels best).
Anway, apologies. The rift was a complete accident on my part; Just a side effect of a failed experiment of trying to create perpetual energy. Although, I should've been suspicious when some nearby kelp turned into celery. Ought to have fixed it when I saw that, really. Once again, apologies. I'll try not to do it again. If it does happen, I think I know someone on this side that can fix it so I can save you the trouble.

Mutant Octopus,
While I appreciate your apology, I do hope that you learn to take better precautionary measures in the future. The use of perpetual motion is excellent in theory, however it mostly just causes problems with the flow of the timelines more often than not. In fact, I have to keep repairing parts of history because of a perpetual motion machine in the future. It just keeps on jamming up all the gears and pipes that keep things running smoothly in the past.
Why I remember the first time I had to deal with the little blighter, it caused my timey-whimey detector to toot instead of whistle, and then froze a chicken egg at twenty paces. Yes, that makes a very dangerous thingie that throws shards all over the place.
The Doctor.
