There are many things you could consider, but they may depend on your budget and locations
If you always film from your bathroom, maybe a change of scenery could be nice, but that may mean scouting locations or renting places such as hotel rooms. And with that, comes the cleanup/protection which would drastically add to the production time.
Another thing you could try would be different (or multiple) camera angles, filming in slow motion or from above/below, but that again may require some investment of more equipment/tripods etc
If you're into story telling, you could create different characters (along with costumes) and scenarios that involve getting messy. For example, a "blackmail" scenario where your puppy is dognapped and a ransom note arrives telling you to cover yourself in something and film it and send to the dognappers or you'lll never see him again. Or a scene where you're making enough custard to feed the extended family and you "accidentally" fall into the bathtub as you're mixing it
Opening yourself up to suggestions here is always good, as here you will find potential customers, so if you can do something people are willing to pay for, perfect, but it should also be something you enjoy too. When play becomes work, it kills the magic a little
Good advice from ImSlaym. Especially when it comes to keeping it fun. If you're having a good time, your audience will follow you - even if it takes a little time to build it up!
Think about what the favourite things you like to see are that really entertain YOU and how you can best replicate those scenarios with what you have.
There's that old joke "we'll fix that in post (production)". But to some degree that's very true. Capture as much as you can so you've got plenty to play with.
Practise editing. If you are working with one model - or alone there are so many ways you can switch things up with editing. You don't need to speak dialogue in real time, you can cut it and get the best bits without the fluffs.
Also, you can set a scene with non-messy pre-ambles in a different place. Film yourself in your wam outfit out in the street, or another location.
Here are some activities that have helped me get new ideas (also, some of my ideas just come to me as I'm living normal life, taking in other entertainment - so know sometimes a creative block just needs you to not focus on it to resolve itself):
1) Go to a dollar store and buy things to splosh with - I've found I'm more adventurous on trying something new when it's only a dollar. It's like a sampler platter! It's led me to be like oooo I need to buy much more of X and do a full scene with that!
2) Go to a thrift store with a set budget beforehand (I tend to do 15). Put together a look with your budget and then decide who is this character? How would they get messy? Would it be intentional or by circumstance? use this answers as inspiration for a scene! (You don't even have to buy the costume or shop in your size, BUT if you do - hey, you've already got your look to trash!)
3) Take a piece of paper and write out categories, such as Splosh, Setting, Character, etc. For each category write 6 options (don't let realism ground you). Then take a die and roll it for each category, writing down which option the die picked. Then put a timer on for 5 minutes and using the string of options you rolled. Free write for five minutes on (for example) How a pirate wench (character) playfully (mood) gets messy with condiments (splosh) in space (setting). What you end up writing may not be anywhere close to what you end up doing, but it gets your creative juices flowing again.
Love you, too
