I wanted to make sure everyone knew this before they started comenting on how this mouse could be included in the Grandmaster page. Most people don't have this mouse and are higher than Grandmaster as it is a new release. The page and section will be moved into the Grandmaster section once most people have caughten this new mouse.
Collecting the cheese for this mouse can be done two different ways. Both ways you need to have caught the Master of the Dojo mouse before(twice if you follow this guide through the Grandmaster and Ledgendary ranks). The first way has a risk to it as there is a chance that you don't get the cheese you want from it but you get a higher amount of cheese by taking this route. You need:1 Onyx Stone, 1 Curds&Whey, and 1Ionized Salt. This will give you an item called Unstable Curd and it is under the Special section of your invantory. When poked it can turn into any number of different cheeses including Onyx Gorgonzola(the cheese you want for the Sensei). For all the different possibilitys of poking the Curd click here.
The other way is guarenteed to give you the cheese you want but it will not give as much as the Unstable Curd. The recipe for this is: 1 Onyx Stone,6 Ionized Salt, and 20 Curds&Whey. This give three pieces of the Onyx Gorgonzola cheese instead of at least 8 from the Unstable Curd. I recommend taking the Unstable Curd route if you have more than 3 Onyx Stones but the safe way if you don't.
There isn't much to say here, you must have at least the Ambush Trap and your strongest base(Explosive if you don't have any Limited Edition Traps/Bases). If you have a stronger tactical trap like the Horrific Venus Mouse Trap(from Nerg in the Tribal Isles) then use it. Luck doesn't play a large roll in catching this mouse as it is the most powerful mouse in the game as of its release but it is always nice to have the luck on your side.
The Dojo Sensei Mouse is very tough and can take a lot of misses to finally catch one. There isn't much of a strategy for this mouse other than what I put in the Trap set up section along with just sounding the Hunter's Horn and trying to catch it. More important though is the loot it drops. It drops the Onyx Mallet Blueprints, the Time out upgrade(for the NannyBot), and it could drop a Master's Seal or extra gold. The Onyx Mallet Blueprints are for a new physical trap that is very powerful(about par with the RhinoBot). The Time-Out upgrade is only available this month(March) and will be useful for upgrading the NannyBot in the future. The Master's Seal is useful for picking up an extra piece of Rumble and possibly getting another Master of the Dojo which can lead to catching another Sensei mouse. For info on the Onyx Mallet trap click here. There is no current info on the Time-Out upgrade(can't be used yet) but when it can I'll have something written/a link for info on that as well.
