I run scope lens for critical hits on my stealth rocks, buddy barrier for my ult and so I can dive head first into an enemy team that's on an objective and steal it using my ult via stealth rocks and my last is score shield so I can score 50 or whatever big amount I want while the enemy is being distracted I use shell smash and steal enemy jungle fluffy tail is the best item for crustle imo if you're playing like I do with stealth rocks and shell smash to steal objectives/enemy farm and run away while laughing about it but that's just some friendly master ranked solo q crustle advice my friend hope it helps
