Wetlook World Forum

Can anybody help, many moons ago I saw a film whilst in hospital, I think it was sone kids/family film think it might have been on channel 5 in the uk

I think the film was about s group of kids n bmx bikes sprung to mind but at the begging of the film, I seen to remember a woman in brown boots n tights with a skirt n she ends up wet In this fountain I think I'm sure she was a bad guy trying to catch the kids for sone reason anybody have any ideas what this film was called oh I'm pretty sure it was American, it was a good wet tights scene cheers...
