Hey jammers! I just got the wackiest glitch, look at these crazy pictures! Click each one for full size strangness.
At first I just went to a parallel of my den, (you can tell it's parallel because there is no furniture) and saw my and all that.
Suddenly I came to a den with a mixture of my treehouse den and Deep Blue! I was an invisible shark as well, and I couldn't find my clone. Weird...
I'm pretty sure it works for any den, you just need to transport to it last second. Then name of your den shows up, but it certainly doesn't look like your den!
Strange! Try it out, jammers, it's pretty hard.
