Hello fellow iblers!
In the sake of tradition of my K'nex contest entries I present to you another hungry game, Mr. Mouth! Mr. Mouth is one interesting species of frog and seems always willing to eat at the expense of your enjoyment. He spins while snapping his mouth in hopes that you can successfully catapult a food into it. This may seem bizarre but this technique has left it a popular game in most households. I have taken time to duplicate this strange species of frog into K'nex form so we can all marvel at its strange eating habits. So, lets build this thing shall we?
Before we begin, please glance through the instructions and make sure you have enough green connectors and y-clips. Also make sure to have the two port motor and a large K'nex tire available. Also, if you haven't already, please vote for this project in the K'nex Contest!
Thanks and Enjoy! JonnyBGood
See it in action here!
Step 1: It's All About That Base...
Sorry, couldn't help that title.... but there's plenty more where that came from. Overall this is a feel good step, very straight forward and easy. Just build what you see in the pictures. The one catch is to please notice that there are three white connectors in the center of the base that are snapped together with two white rods. The blue rods are attached to the middle white connector.
Also for the curious builder / modifier , yes, you need that tire rubber there. It supports the rotation axle and prevents the frog from tipping over every time he shuts his mouth. The mouth weighs a lot on this animal, since it seems to make up 90% of its body.
Step 2: Power Jaw Assembly
Okay, so this is where things get interesting. In this step we got a lot of stuff going on starting with the large bottom plate. The next pictures show the assembly of the front bottom lip of the mouth, which leads into a very interesting feature of the animal. This frog has it's brain and all its muscles in its mouth.... When assembling this part make sure to notice how the motor assemble inserts into the frame. Also ensure the battery pack is attached to the white rods as shown in a couple pictures in this step. The battery pack acts as a counter balance to the frogs enormous mouth. As you continue through the step you will eventually finish making one side and then the picture shows two sides. That is because you will need to mirror what you just built on the other side of the mouth. After your project looks like my picture continue on to attach the spin axle onto the bottom of you assembly. Then attach your Power Jaw Assembly to the Base.
Step 3: The Thinking Cap
Okay, so its not really a thinking cap if it's got a brain in it's mouth.... but still stereotypes are hard to get by...
Anyway so now let's build the Thinking Cap! Unfortunately I couldn't think of a way to break it down in a way that seemed logical, mainly because like all other parts of the project, it is frame that I threw pieces at until it looked full. So when building this, I suggest a similar approach. Start by building the main structure of the part by ignoring all those loose pieces and only build what would logically hold the assembly together. After you have the main structure start snapping on all those green connectors on the front and start systematically adding more features until it looks similar to mine.
When your done, you're ready to attach the Thinking Cap to your previous assembly. The rear of the yellow connector snaps onto the yellow rod as seen in the pictures and you ready to go! All you need are some Catapults, and they're cover in the next step.
Step 4: The Catapult
Natives, upon finding this species of frog would use small sapling trees to catapult insects into the frogs mouth.
Since we are in a more modern environment, this small catapult should suffice. The Catapults construction is relatively straight forward and similar in difficulty as the Base, just with more pieces. Once you are finished you are ready to play! Make yourself some insects and load them as shown into your catapult. After that its as simple as pulling the catapult down and slinging them toward the mouth of a hungry frog!
Step 5: Finished!
Thank you so much for building your own K'nex Mr. Mouth! I really appreciate building these awesome games for the K'nex contest each year and I hope you enjoy building it as well. As for this frog.... it seems it will live it's life in the same glory it has since it's creation. Games just have this wonderful thing of being enjoyable in every form and I'm glad that I could build another one for the site this year!
Thanks again, and stay awesome!
