fidgeting?

so i have this fish i keep in my bag,he's some kind of fishing lure?he's squishy and i use him when i travel,the problem is he's kind of fragile,considering he's been glued back together several times i can't continue to use him,so my plan is i have some clay and i can make this shapes,i definitely wanna make a circular one with a hole in the middle(a donut,but i don't want it to be a donut),does anyone have any other shape recommendations?preferably small enough to keep in a pocket for travel
