Thunder

Thunder is a lava sea creature that can be fished from any lava on the Crimson Isle.¹

Requirements: Fishing level 36 and the Novice Trophy Fisher title from Odger.¹
Chance: base weight 40, which works out to about 0.86% of sea creature catches (1 in 116) with every sea creature unlocked. Whale Bait multiplies the weight by 1.25, and so do Light Bait by day and Dark Bait by night.¹²

Attacks. Each attack that lands charges an Empty Thunder Bottle:¹

Attack	Effect	Bottle charges
Jump slam	leaps up and crashes down on players below it	20
Eye laser	2,000 damage to a nearby player	10
Sea Lantern strike	marks a circle around a player; after 1 second a Sea Lantern lands in it for 15,000 damage	5

When it dies it bursts into 5 to 9 sparks; a Pulse Ring raises the count if you are within 20 blocks. Right-clicking a spark with an Empty Thunder Bottle adds 250 charges.¹
