hey, so like
toys arent being used to their fullest potential
what if you did something like (ROBLOX WARNING, COVER YOUR EYES!!!!!!!!!!!!!)

The 4 String Roblocaster premiere guitar (https://www.roblox.com/catalog/14492601/4-String-Roblocaster-Premiere-Guitar)

or like Trollamon (https://www.roblox.com/catalog/105189783/Trollamon)

this could give Bopimo! the diversity of levels that the game REALLY needs, like fighting levels, skateparks, etc.

i understand completely that Bopimo! is trying to stray further away from the big-boy ROBLOX games like Brick-hill and Polytoria, but at the same time, its starting to get stale, the most creative you can get is using speed changing and NPC usage, and by itself, thats the bare minimum. I get it, limitation breeds creativity, but Bopimo! is too limiting with its levels to the point that how much can be done before it becomes just another quirky online ROBLOX rip-off game with the twist being "oh its mario 64".

i just think it would be nice.

yea dude

if you mean doing gameplay stuff like with your second example (thing that does damage to people), then no.
i do think toys could use some functionality, not just being something you hold - maybe a water gun toy that lets you shoot out water (cosmetic), or the fireworks being able to be placed down and flying into the air then exploding. i've suggested in the past maybe giving certain items (swords for instance) unique animations when using the Q key to punch (making them look like you're slashing or something).
toys aren't meant to be useful in-game, they're cosmetic like hats, clothes or faces.

power-ups are a thing that might be added later i think which will actually have effects on gameplay. not sure what they'll be but probably mario-esque ones like being able to shoot fire and things.
now i did at one point suggest a weapon block that lets you create a weapon (with an item's mesh and customisable colour) that has a certain range, damage value, cooldown between hits and stuff but it was rejected cause it was limiting or something. i'd still like to see that in the game and it could be fun.

tl;dr
the point of toys is to be cosmetic - not to do gameplay stuff. they could use more life and cosmetic functionality personally, but actual gameplay thing like power-ups will come later

This is not gonna happen
