advice for some fun encounters

[STARGAZER_DRAGON]

Looking to get some ideas for some fun encounters. Let me give a rundown of the party right now

Party will be lvl 9 soon, currently

the party:

Hobgoblin Gunslinger, Uses revolver (house ruled targets flat footed AC)

Orc Barbarian, Actually was a hobgoblin but was reincarnated as a orc.

Dwarf Anti paladin -Uses 1 handed weapon and shield plans to use shield smash and duel wield with shield.
( do to some story reasons he heals from negative energy and is harmed by positive, radiant vulnerability 5, light sensitive)

Goblin Monk 4 Ninja 4
Has flurried feint so he is able to sneak attack often

Human Sorceress
Also is healed with negative energy and harmed by positive, dark-vision, light sensitive

NPC Goblin Alchemist
Sub-optimally built, besides bombs is more of a merchant build then anything and is main supplier of potions including healing potions, for a cost of course. But does help in combat via bombs and alchemical fires

The party is mostly experienced player with only the caster being inexperienced, they are pretty decently built and can dish out good damage and take a healthy amount with average damage bonus of 15 and average to hit being around 12-15

The area and basic info:

Right now the anti pally has a small temple and the leadership feat but his cohort stays in the temple to run it, the gunslinger also has leadership but his cohort takes care of the the parties stronghold that they have managed to make. They are pretty weakly geared do to a recent near wipe that cost the most of there gear and they have spent a lot building up a small stronghold and hiring a small band of goblins to defend it.

Thus far they have had run ins with the human kingdom to the east, to the north is some giants but they have ben sticking to the mountains, the south is mainly weaker stuff (was the starting area) to the immediate west there is a swamp with some kind of befriended hags more like weak alliance and also a decent sized lizard man tribe that's growing. (that's where they lost there gear to)

Think that's a pretty decent description right now

any idea?

A Paladin + entourage come across the party and immediately assume the sorceress is a damsel in distress, captured by these vile monsters. The paladin demands her immediate release!

[STARGAZER_DRAGON]

Would be interesting, would have to have him convinced that she was being mind controlled or else things would go south soon as she fireballed the pally lol but it could be fun encounter

[VRMH]

If the troupe of do-gooders seems to be escorting something (someone?) valuable, it could even be an option to play along for a bit.

Fun encounters, eh?

Encounter on a See-Saw

Boulder Trap Encounter

The Golden Idols

Disintegrating Battlefield

Any of those strike your fancy?

[MiniGM]

Power Rangers?

An arena that they can challenge at any time an be teleported there to place bets for anything but the catch is if you lose you lose something of equal value. Like a elf betting his or her low light vision for dark vision so if the elf wins it gained dark vision,if it loses it loses its low light vision. You can also bet your life for the return of some one elses.
