Full review, as promised. I think your theme is brilliant and, even if a giant cartoon bunny may not be 100% appropriate for the universe of League of Legends, there's definitely a niche for a not-too-serious character who gets to break the fourth wall. Your abilities are imaginative and thematically well-aligned, and I can see Catus Lepus working well as a support. My main criticism is that his abilities are a bit difficult to understand, though that might be more of a phrasing issue than an implentation issue, and his ult could be something a lot more interesting. Here's what I think of his abilities:
 * Your base stats look mostly fine, and my only concern would be Catus Lepus's basic attack range, which looks overly high. Any attack range over 550 usually indicates that you want your champion to be good at poking and attacking from safe ranges, which is pretty much the opposite of his theme and playstyle. Making him melee might be a better idea, even if he happens to have a wand, since it'd go well with him ambushing enemies and being the center of chaotic fights.
 * Hysterical Laughter is brilliant and perfectly in tune with a cartoon character. I also like how it encourages a support character to ambush opponents, which opens up gank opportunities and forces an unconventional character to also play unconventionally. My only real advice would be to clean this effect up a little: the anvil effect doesn't do much and could be moved to something more interesting elsewhere, Hysterical Laughter should probably just last as long as Catus Lepus remains in combat, instead of having multiple effects prolong its duration, and the effect itself should probably specify that it works only on champions (e.g. Catus Lepus gains Hysterical Laughter upon using an ability against an enemy champion who doesn't see him).
 * Smashing Hammer's base effect looks awesome, and while I'm generally not a fan of item scalings on hard CC, this one looks surprisingly fine. I also love the spam effect attached to Hysterical Laughter, as it's really thematically appropriate, but as it's currently phrased the effect looks a little confusing. If you want, I can help you with the format for writing down Catus Lepus's kit, but here I also think you should try going for a simpler spam effect (e.g. while Hysterical Laughter is in effect, Smashing Hammer has no cooldown but targets recently hit by it are slowed instead of stunned).
 * Mischievous Mayhem is intriguing, though the effect looks like it might be a little weird in practice: as PrimusMobileVzla mentioned, currently the hat effect looks a lot like stealth, and as a result the Hysterical Laughter shield doesn't look like it would help. I also think the poison effect is a bit much, as LivesByProxy pointed out, and also not that appropriate for a light-hearted champion. I think you should probably redo this ability while keeping the hat theme (e.g. Catus Lepus throws down a hat that poofs everyone around it, ally and enemy, into it, letting them blink out after a short delay, and Hysterical Laughter causes it to polymorph enemies into cute little bunnies once they exit).
 * Tricky Shot's base effect looks great, and I think the idea of a smoke screen is good too. However, I think you should probably go with a proper smoke screen, e.g. something like a where everyone inside turns invisible, even when attacking or using spells, like in one of those cartoon fights where everyone gets into a brawl and the only thing you can see is a big cloud of angry dust and the occasional head rearing out. The current blind and silence, by contrast, doesn't look all that fun, and I don't think Catus Lepus should be particularly good at controlling his opponents; rather, he should be all about making fights get completely out of control.
 * On All Fours is my least favorite ability in Catus Lepus's kit. It's not all that funny or goofy, it doesn't really mesh well with his kit beyond letting him roam a bit better, and it's not really a new contribution considering has pretty much the same effect (I understand you made this kit well before her rework, but you need to take it into account now that it happened). I think this ability would be a lot better off if it were some kind of massive comedic gag. For example, you could take the anvil effect from your passive and have Catus Lepus drop a giant anvil on top of a target enemy after a large delay, which would squish them and every enemy around them on impact, with ranks increasing the weight (e.g. rank 1 would be a 1-ton anvil, rank 2 would be 10 tons and rank 3 would be 100 tons, to reflect an increase in AoE width and squishing power).

All in all, I think this is a brilliant champion concept with a kit that has a lot of fun effects. The main issues you're going to have to deal with now are mostly clarity, cohesion, etc., but aside from that you have an awesome idea for a support that I think could genuinely work and stand out from League's current roster, in a really good way. There's an untapped thematic and gameplay niche for a chaotic slapstick champion that Catus Lepus would fill perfectly, and with a few tweaks you could have a champion that would be on par with League's official design.
