Hey there. So, I went out of my way to remeasure all of the monsters in Eliatopia. The player's height was, at the lowest point (https://prnt.sc/pooaal ), 127 pixels tall. That's a smidge higher than 120 pixels in the Flash version of Eliatopia. Because of this, I remeasured all of the monsters. Bear in mind, the average human is 5'9" (1.7526 meters). Without further ado, here's what I got.:
Squisher: https://prnt.sc/poobn0
32 pixels, 1.45 feet/0.44 meters
Fanged Squisher: https://prnt.sc/poob3s
34 pixels, 1.54 feet/0.47 meters
Petunia: https://prnt.sc/pooat7
117 pixels, 5.3 feet/1.61 meters
Spiked Squisher: https://prnt.sc/poo9xb
46 pixels, 2.08 feet/0.63 meters
Shagdaw: https://prnt.sc/poo8p2 (Yes, I had to trap him in a fence to get him to hold still)
60 pixels, 2.72 feet/0.83 meters
Ground Spitter: https://prnt.sc/pood7q
94 pixels, 4.26 feet/1.3 meters
So yeah, there ya have it. Hope this one's more accurate.
