Hi, this is how I made Jinx's chomper grenade, so (maybe) you could (hopefully) make one too (in case you'll ever want to)

With a lot of cardboard and some more paper!

I. GATHER REFERENCE PICTURES I used mostly fanmade 3D models and one or two screenshots from the actual show - that's why my chomper isn't exactly show accurate. I was trying not to go too hard on myself (for a change), so I didn't care about accuracy that much - do as you please.

For gathering refs I use Pinterest and Twitter accounts that share high quality screenshots (eg. this one).

II. PLAN OUT (the hardest part) Time to use refs to sketch the chomper - I started with a rough sketch to get familiar with the structure and all it's elements, to help me better understand how to build it. It was done keeping in mind estimated measurements I was going for (highly recommend using checkered paper), but keep in mind a 2D representation won't fully translate into 3D, so it wouldn't turn out the exact same.

When I was done with the rough sketch, I made a second, cleaner one (in pencil), this time to measure things more exact. Then constructed the "target board" you can see above it. It's representing all the "layers" - the cylinders that once stuck on top of each other would make the grenade - so I know how to space them out. It's basically a top view of the grenade without it's jaws.

III. MATERIALS, TOOLS and how I work with paper (important) List of the most important stuff: - different types of paper* - wood glue and/or any good paper glue - paper masking tape (or any that can be easily removed) - acrylic paints - compass (the one for drawing circles) - hobby knife / exacto knife / box cutter - hot glue gun (optional, but makes things easier) - air dry clay (optional)

*I used 4 types: - magazine paper (super thin, I used supermarket flyers) - cardboard packaging paper (from rice, cookies etc., rather thin but a lot more sturdy than regular paper, easily bendable) - super sturdy cardboard (still looks thin, but it's so hard it breaks easily when bend too hard) - corrugated cardboard (thick, but can be squished to be thinner; a pain to cut with scissors - recommend to use a knife)

Tips for working with paper: - scratch the shiny, printed side of the cardboard packaging to make it easier to glue (you can also try to gently peel it off, but it's not always possible) - another gluing tip: use masking tape or clippers to hold elements together before the glue starts to work, otherwise you may have to hold them in your hands and wait forever - if the paper is thin enough, curl it up to fit before gluing it onto a rounded surface (I mean something like this, except I just press it against a table and not my finger; it can be done with any tool really - scissors, ruler, pencil, edge of the table etc.) - the magazine paper can be used like a sculpting medium (bent, twisted, crumpled into balls etc.) to fill any empty spaces and even things out - I used it to make a "beveled edge" on two of the cylindrical parts, that's why they're covered in colorful stripes

IV. CONSTRUCTION (best part) Time to build some cylinders (how exciting!). I started with the tall middle one. Do I have to explain it? Just remember to add the details (the "bars", aka two layers of cardboard packaging paper spaced evenly) to it before you glue all the parts together.

For the thinner cylinders I simply glued circles of corrugated cardboard together, then covered the sides with a strip of cardboard packaging paper bent to shape. Depending on how tall the cylinder is, one can cut out two circles (top and bottom part), then sandwich (glue) some more scraps inbetween and cover the sides.

Now onto the two tricky parts: 1) Bottom I cut a ring out of the sturdiest cardboard I had and built an armature on top of it. It was then covered with magazine paper strips dipped in glue to create a half-sphere (basically paper mache). I filled it with even more crumpled paper to help hold the shape.

To make those funky "bolts" I scruffed each of those parts a bit a the bottom by cutting about 5 mm into them, so the paper would bend inwards allowing it to better fit the uneven surface. Then glued on the caps (this is when I run out of patience, filled the "bolts" with hot glue, placed random scraps on top of each one and then cut them into shape ..whatever works).

When you have everything assembled and it doesn't look the best, you can use more magazine paper to try to fill any gaps. Even better if you have air dry clay (that's what I used to even the half-sphere a bit). It's great for smoothing out the transition between parts if mistakes were made. If you want to make it super smooth you can use sanding paper.

2) Chompers (most important) I planned out the jaws on checkered paper, constructing the shape by following the lines or making diagonals, so it would be easy to replicate and make adjustments (super easy to measure).

It was then traced and cut out of cardboard packaging paper. I connected each part using masking tape to shape it into a jaw and check if it fits the grenade - after some adjustments were made I glued everything in place.

I wanted the jaws to be thick, so up to three additional layers of corrugated cardboard were cut out and glued on the inside of the initial "sculpt" - this allowed me to carve the eyes through the first layer.

V. PAINTING (suffering) general tips, because I'm not an expert - I used acrylics and started with painting everything black, then color and simple shading, then highlights (thin, bright lines on the edges), and paint splatters at the very end - the layering allowed me to later scratch some of the paint off to add more texture - follow your refs closely, you can even pic colors of off them (using a graphic software or any color picker online) to hint what to mix (eg. the jaws had a greenish/blue tint, so I mixed a bit of green paint with black and white)

- more on that note: just try not to use only black and white (that's what I did on my first try, when I forgot how painting works) - on the final version even the bottom part (which may seem plain black) has a drop of red or brown added; the highlights are not purely white either - it takes a lot of time and requires angelic patience (took me 2 days); take a break if you get too angry or frustrated

And I think that's it!

It's my first time trying to explain stuff and I wasn't sure how much detail to include, so if anything's unclear or missing I'll update the post. Feel free to ask and point out stuff, I'll be happy to help!

Good luck have fun
