Ninjago, Season 7: Hands of Time

Nya:
The corrupted code seems confined to Zane's secondary systems for now. I can temporarily reroute his memory functions through the Samurai X Computer to buy you some time, but not much.

Kai:
That means if we don't solve these puzzles soon, Zane might lose control...for good.

Nya:
What's the next puzzle?

Jay:
Ooh! It's a riddle! Lucky for you guys, I'm even better at riddles than I am at puzzles. Haha. "Feed me and I grow, always hungry. Give me something to drink and I die, always angry".

Kai:
That sounds like it could be Fire. These symbols must be the possible answers! Look, there's a tiny flame!

Nya:
Careful. One wrong answer could break down the rest of Zane's security system.

Jay:
Lightning bolt, drop of Water, Smoke— Ew! Is that a foot?

Zane:
The foot symbol denotes Speed. This appears to be a puzzle about the Elemental Masters.
