Katara drop list?

Where can I find lvl50+ Katara? I know Harps drop lvl70 ones, and I got a few lvl 80 ones at Kentaurus, but I need a lvl50 right now. Help pl0x?

I've gotten:

Level 40 from Freezers or Sparkers (Aqua Road seals).
Level 60 from Homuns at Magatia.
Level 100 from Memory Guardians.

If you've got the coins, I think you can get the level 50 one off the Carnival PQ fat man.

Edit: My brother told he got a level 50 Katara from Male Mannequin at Kerning Square.

Of the ones I've found:

70; Red kents
80; Black kents
90; Afterlords(In Neo City)
100; Memory Guardians

Haven't really looked for them, they just drop like they're going outta style where I hunt for other things. ):

Level 50 katara drops from Male Mannequins in Kerning Square. I can confirm this as I got one myself

Level 90: Master Death Teddies. Like candy.

You can get 30/40/50 from trading in Maple Coins.

Level 30/40/50: Somewhere in Kerning Square, don't remember
Level 60: Homuns
Level 70: Red Kents
Level 80: Black Kents
Level 90: Master Death Teddies

That's all I've found.
