YES!
If you live in Long Beach then the mudskipper is 20bux. 5 bux more if you live really far away, like San Diego. If you live in the LA area it's just 23bux.
As an option, I'll throw in 2 fiddler crabs for you. The temporary setup of a 5 gallon would be an additional 7.61 bux, and the fiddler crabs are 5.86 each. If you want a little critter keeper setup for both, that will just be 3.11.
If you want an individual setup for EVERYTHING that would be 15.61 bux, these things are hard to make for me, srsly. And it would be somewhat of a discount, I believe.
