There are 188 legs in all
<h2>
Step-by-step explanation:</h2>
Let's solve this problem step by step:
1. First of all, there are 4 unicorns enjoying themselves playing in the forest, they are: Stardust, Umo, Windthorn and Highflyer are enjoying themselves playing in the forest. Each unicorn has 4 legs, so:
![4 \ unicorns \times 4 \ legs=\boxed{16 \ legs}](https://tex.z-dn.net/?f=4%20%5C%20unicorns%20%5Ctimes%204%20%5C%20legs%3D%5Cboxed%7B16%20%5C%20legs%7D)
2. The unicorns notice 8 spiders in the tree, so each spider has 8 legs. Accordingly:
![8 \ spider \times 8 \ legs=\boxed{64 \ legs}](https://tex.z-dn.net/?f=8%20%5C%20spider%20%5Ctimes%208%20%5C%20legs%3D%5Cboxed%7B64%20%5C%20legs%7D)
3. There are 5 cockroaches, so each cockroach has 6 legs. Accordingly:
![5 \ cockroaches \times 6 \ legs=\boxed{30 \ legs}](https://tex.z-dn.net/?f=5%20%5C%20cockroaches%20%5Ctimes%206%20%5C%20legs%3D%5Cboxed%7B30%20%5C%20legs%7D)
4. There are 7 bees, so each bee has 6 legs. Accordingly:
![7 \ bees \times 6 \ legs=\boxed{42 \ legs}](https://tex.z-dn.net/?f=7%20%5C%20bees%20%5Ctimes%206%20%5C%20legs%3D%5Cboxed%7B42%20%5C%20legs%7D)
5. There are 3 deer, so each deer has 4 legs. Accordingly:
![3 \ deers \times 4 \ legs=\boxed{12 \ legs}](https://tex.z-dn.net/?f=3%20%5C%20deers%20%5Ctimes%204%20%5C%20legs%3D%5Cboxed%7B12%20%5C%20legs%7D)
6. There are 4 cows, so each cow has 4 legs. Accordingly:
![4 \ cows \times 4 \ legs=\boxed{16 \ legs}](https://tex.z-dn.net/?f=4%20%5C%20cows%20%5Ctimes%204%20%5C%20legs%3D%5Cboxed%7B16%20%5C%20legs%7D)
7. They notice a pair of antlers behind a bush, so this means there are 2 more deers, and each having 4 legs. Accordingly:
![2\ deers \times 4 \ legs=\boxed{8 \ legs}](https://tex.z-dn.net/?f=2%5C%20deers%20%5Ctimes%204%20%5C%20legs%3D%5Cboxed%7B8%20%5C%20legs%7D)
7. They notice a pair of antlers behind a bush, so this means there are 2 deers, and each having 4 legs. Accordingly:
![2\ deers \times 4 \ legs=\boxed{8 \ legs}](https://tex.z-dn.net/?f=2%5C%20deers%20%5Ctimes%204%20%5C%20legs%3D%5Cboxed%7B8%20%5C%20legs%7D)
Adding all the amounts of legs we have:
![Total=16+64+30+42+16+12+8=\boxed{188 \ legs}](https://tex.z-dn.net/?f=Total%3D16%2B64%2B30%2B42%2B16%2B12%2B8%3D%5Cboxed%7B188%20%5C%20legs%7D)
