Big animals are animals which are classified as big based on whether seals, hydras or owls can smash them, as seals and owls both have upgrades only allowing them to be able to smash small animals. They are unaffected by seals sliding on ice and owls, and if the player uses any of those three animals to smash a big animal, the effect will be the same as running into a wall. Usually they can be defined as anything that can smash trees while on the ground by default (usually bigger than an owl).
