Burrow watched on while Mr Growls shoved a silver circle with a strange red, green, blue, and yellow symbol on the non-shiny side into the log that had just been picked up and washed out. The biped jammed it in tight, shiny side pointing out with the circle filling up one end completely. Then, Mr Growls went for a white box in his chest, pulling off shiny squares with alien writing on them and sticking them around the circle to seal up any gaps with the log. Next up was the hole in the middle of the circle, Mr Growls covering it completely before putting the construction materials back in his strange chest before holding the log out towards him with pride.
