I would use PVA glue to insure that all the pieces will stay together and a tooth pick to spread the glue onto the flaps and the pieces. Please, if you have any suggestions on what I should design next (I am mainly focusing on doing mods) please comment down below!

PS: you do not have to glue on the head like the one in the picture.
