It was with a boy and he would go into his treehouse or shed and talk to these aliens and there were like 5 of them, and the boy would go into some kind of wormhole or something and fight people or something... did the show have a title like "bucket of slime" or something like that.. I can't remember too well I was real young, it must have been shown in the late 1990's... I think one of the aliens eat nails and there was a girl alien, one or all of them were really slimey and gross, it wasn't a cartoon though.. I just can't remember it. Help please!

Sounds like the Disney Channel Original Movie: Can of Worms (1999)

Thanks so much! That's the show! I haven't seen it since I was 6 lol
