I have seen a few errors in the Grammar from interacting with toys, such as a Jacana leg.

Jacana Leg:
Your lion spends whole day dragging the funny leg around. There are no more uses left for this item!
The word "the" is missing from this sentence, between "spends" and "whole" I would really appreciate if that was fixed.

Submale sparring:
Sparring with a sub costs 10% energy - make sure you have it spare!
The word "to" is missing between "it" and "spare."
It would be even more useful to fix this error, since you have a chance to see it every day, before sparring.

Finding cacti in explore:
You find a cacti with juicy pulp! After some witty manipulations with a stick in your mouth, you manage get a lot of needles squished!
This sentence is missing the word "to."

White crowned Shrike Explore encounter:
A White-crowned Shrike flies above savannah.
The word "the" is missing near the end of the sentence. Please have it fixed.

Guiding the Migrating herd in explore:
You know this territory well and guide the herd gently through the crocodile infested river, making sure there'll be plenty wildebeest to hunt in future.
The word "of" is missing between "plenty" and "wildebeest." Please fix this in the future.

Following the Water Patrol:
You follow the humans silently, and they lead you to a source of water. Being the king of beasts as you are, you decide to drink right away, don’t minding the humans taking pictures of you.
Instead of the word "don't" the word should be "not."

Playing with an Elephant skull:
Your lion enjoys playing with the skull, scratching it and biting funny tusks.
The only word that is missing is "The." It should be located between "biting" and "funny." Please fix this.

Eating a Small Bird Carcass:
Your lion gnaws the tiny bones and gulps the feathers down. Bleh. There are no more uses left for this item!
The first sentence is missing the word "on" in between "gnaws" and "the."
