Web Bomb

A Web Bomb was a weapon Gargamel used with his flying contraption in the EMPATH: The Luckiest Smurf story "Handy's Flying Lessons". It is a black spherical object that, when it strikes its target, encases it in a thick black web from which it cannot escape.

In the second part of the story, where Gargamel uses his flying contraption against the Smurfs, the evil wizard unleashed web bombs on the Smurfs to trap them all. However, Handy escaped being captured and got into his smurfplane to disable Gargamel's flying contraption.
