With the right download boost and max EVS/nature it essentially has 200 base attack or special attack. That's absolutely ridiculous when you factor in its movepool and typing. You can prepare for the Rock Polish set all game, but theres still a chance that it can get one turn to RP and sweep.
Growlithe is seriously one of the cutest Pokemon ever.
Another cute one is Wingull. It's so underrated in cuteness. Can you imagine being on a beach while Growlithe is trying to build a super sand castle wall cause it's scared of the water? And then Wingull is just flying around laughing at it's little brother before landing on the sand fortress. SO CUTE. And then when we walk around Growlithe will get to run about while Wingull just sits on your shoulder like a parrot. They'd be sooooooooooo amazing.
They would also get scared if there's a thunderstorm, which I haven't figured out how to stop yet. Maybe an Exeggutor too. He can like the retarted uncle hanging around. But he's a palm tree that provides cover so we can just chillax against the silly dopey dude.
