Electro Spumes hide in the sand and pop out only to shoot passing prey by spitting rocks from their mouths. Electricity courses across their body, so you can't hit them with sword attacks. They're not very smart, though, so if you roll a bomb their way, they'll unwittingly go down before they even know what's happening.
Ampiluses are crabs that once inhabited the Lanayru sea... but in the centuries since they've evolved and become electrified! They roll around in their round shells to attack. If they touch you they'll zap you and then come around for another pass. Use your Shield Bash to stop their momentum and stun them.
The Bokoblins who have invaded the desert region have also laid hold of much of the old technology there, including electrically-charged swords and gadget-equipped armor. Strike their swords with yours and you'll get zapped, leaving you open to attack. You'll have to be precise to win!
One of the ancient robots you rescue in the desert will revamp your Beetle to make it even more useful. The Hook Beetle can use its powerful mandibles to grab onto small objects like Bomb Flowers and carry them around. It can also drop its payload on any targets immediately below.
