Just wondering since it had a TD release I think. A very expensive TD game if I recall.

Umm, no. Outside of the general theme, they share nothing.
Just a smidgen of research would have shown you that
Cotton was made by Success, first for the arcades and then ported to the PCE (among others);
Magical Chase was made by Quest for the PCE and later ported to the GBC; and if you check out screen shots and/or youtube footage, you'll find that they are very different graphically (
Cotton is much more dark and moody than the cartoonish and colorful
Magical Chase).
