Original Description:
 
Another one of the first fusions of the old comic fusions that were done by eternalJonathan coming back and enjoying these largely forgotten fusions..That being Princess Universe  
This fusion being of both Princess Cadenza Sparkle (Cadence and Twilight Sparkle) and the fusion Princess Eclipse (Luna and Celestia). All the while eating a particular magic burger that apparently has some interesting side effects…And her majesty seems to be showing the results times 4.
 
Now once more looking at her majesty, we see that she has not stopped enjoying herself, and it appears to show!
 
Done once more the awesome :iconeternaljonathan:
