Summary Here is some Tentacle Lego arms that i created for my son. We can now make great Lego creatures with those ;-). Just replace the standard Lego arms with the tentacles. It is based on the Lego Tentacles by BrianEnigma (http://www.thingiverse.com/thing:582766) and i used some part of the Lego Figurine designed by Alexis67 (http://www.thingiverse.com/thing:734376).
