I just realized that the Tales From The Vet team of Dr. Phil van Neuter and paillis is similar to Twilight Sparkle and Spike, with Twilight Sparkle being similar to Dr. Phil van Neuter, both being smart and giving their assistants the unpleasant job of bringing their stuff to them and Spike is very similar to Mulch, both being the long suffering assistants to their bosses. Another connection i made is how Rarity is similar to Composta Heap, both being attractive and beautiful, and although i myself don't support the couple RariLight, it's an interesting connection i made between the three characters.
