Heres a few!
The 1st is the Scorpion tail! I used smaller bead at the bottom and heavier at the top so it would curl like a scorpion tail.
The next I made with wiffle ball from the $1 sote, blasa wood and nutz & boltz from
Birdsnest Specialty bird toy parts toys The love to spin the nut up and down the thread on the bolt. The yellow bell on the bottom is also from that site.
The 3rd is a thin ploy from Home Depot cut into 3 strings, braid it and tie jumbo beads from same site on the bottom. This also works if you tie the end together in a circle for a foot toy.
