So this I think would be a good addition to the game. What this would do is it would allow you to create bigger and better scents. Say you have 2 rare scents. With either Coins or Bucks, you can fuse them together to create a Large Rare Scent, which could in theory last for 30 minutes and produce 2 creatures at a time. This could go for all scents, excluding Giga Scents as they already last for 3 hours. Then, after fusing into Large Scents, they could fuse into Huge Scents, which could last for 40 minutes instead of 30, again using either Coins or Bucks to fuse them. I think it would be a fun addition to the game as well as an improvement to the scents.
