Putting it as General since there diapers are clean, just getting waterlogged from swimming. (Will possibly change when YEYP posts since i never know if water logged diapers count as wet). Also THAT's NOT ALCOHOL. My characters prefer juice drinks.

Mona and Kimo went to one of Crescent's parties and Merc sits it out since he can't stand Crescent, Lavender did see Mercury at a local juice bar and shocked to see him off work. The two decided to spend some brotherly time together at one of TurtleReef's local spas. Of Course their always wearing diapers and they like them waterlogged.
Lavender and Mercury both prefer drinking juice beverages. Mercury we see having a drink themed after him "The Merc Special" while Lavender prefers bitter juice made from bitter berries, with Mona and Kimo with Crescent for awhile and Mercury's off work, Lavender might just call Venus and Jupiter so the 4 Lugs can spend some family time together. Looks both overdid it at a buffet that Mercury won, looks like Lavender will have to try harder to beat his elder brother at something, till than he's possibly gonna make fun of him while the their diapers drain the spas pool, at least the spa staff will get quite some hardy tips.
Mercury and Lavender do enjoy each other's company, their sisters do their best to see them also since they can be hard to track. Good thing Mercury has a full gut and Lavender might get a chance to tease Kimo before they leave for their Mercenary work.

My characters prefer to drink juice stuff, Mercury has a special drink themed around him called the Mercury Special. Mercury taunted Lavender thinking he doesn't have the stomach for it, which he'll try to prove wrong when he's finished with his Cherri Berry extract. Turtlereef has fantastic juice bars and Mercury can usually be seen in them.
