My shroomish recently evolved during a battle and I'm a bit lost on how to care for her as a breloom. Are there any key differences to look out for and care that used to apply for her that doesn't now? She still is getting used to her new size and tail I've noticed, and I make sure to not get upset if she knocks things over.
Care should remain the same, if they were healthy enough to evolve without issue, then you’re already giving them what they need. Unhealthy Pokemon just don’t evolve without a lot of force. It’ll have an increase in food, it should roughly double to triple in quantity depending on how much energy your Pokemon has to output. If it’s a battler, triple, if it is a house Pokemon, just double should be fine, they do forage while out on walks when peckish, so they’ll kind of do a little self care if needed.
They will have a new abundance of energy in short bursts. They do get the zoomies, then konk out in a shady cool patch, usually under shrubs or near bodies of water where it’s damp and usually full of rotting foliage and debris. Get them a target of some kind if you can’t battle them, like a practice dummy. They will need to release energy somehow if not via natural methods, or you’ll end up with them destroying things out of frustration. They don’t like to be cooped up much either, you may have to increase their walks.
It will in time get use to its new size and shape, they do go through quite a drastic change, but all Pokemon need time to adjust to evolutionary changes, this is not unusual and you shouldn’t be too worried. Best thing you can do is protect your valuables, box them temporarily while she gets use to the tail, it usually takes a week or two to get the back of it, and even then accidents happen. When she’s more in control perhaps have a ‘calm zone’ with all your most precious things in, to go to when you or your Pokemon are looking for some peace and quiet. They do nap a lot so I find having a humidity zone for them is great for indoors. Just get a water tight tray that’s big enough for your new breloom to sleep comfortably in, line it with 2cm of shingle for drainage, another 2cm of soil, and then just pad moss in and mist it loads. It knits together like a bed and they feel very at home on this. A lot of grass types enjoy a moss tray, so keep it in mind for winter. They won’t like the cold and will need some place cosy indoors for them.
