Haven't you noticed all of the robots lately? And how little beast type enemies are showing up? And also how constructs have been always been showing up with in gremlin stratus, but almost never the other way around? And so many of them are like other creatures, but mechanized? This is probably the work of Eggman! D: Here is a list:

Scuttlebot: was a chromalisk
Retrode: was a zombie
Shufflebot: was a jelly cube
Mecha Knight: was a spiral knight?
Gun Puppy: was a wolver
Love Puppy: was a mewkat D;
Roarmulus Twins: was 2 snarbies D;

Also, this game is even published by SEGA! Eggman has definitely made his mark on the clockworks.
