>>39504763I would make this just Immunity to Bug without the trapping effect.
Immunity to Bug stop U-Turn most notably, but also provide free switch-in opportunities.Would also stop Sticky Web I think.
Making a Pokemon immune to Bug while simultaneously trapping it because it used a Bug move wouldn't really work mechanically, except maybe in Doubles, since you need to execute a move in order to be trapped by doing so, and an immunity prevents that.
We might want to add something to the Bug immunity though. Probably a stat increase, or maybe a free heal. A stat increase like would be better at punishing U-Turn (because your opponent would have to switch to escape, meaning you get a free attack on the switch-in) but a absorption effect would add longevity as well as fit the Grass typing's theme of healing.
