Spikes are hazards in Perspective, first appearing in level 3.
Spikes are triangular shaped, with the pointed end of the triangle in an upwards direction. The spikes are coloured in shades of grey and white, depending on the lighting and grouping of the spikes.
Spikes are hazards that kill the dog on contact. In some cases, they must be jumped over to be avoided. In later levels, spikes can be changed into coins with a change of perspective. When the coins are collected by the dog, the spikes that were once coins disappear, even when the perspective is changed back. This can assist the player in some levels with large amounts of ground covered with spikes.
